How To Build New Blood Vessels, Regenerate Muscle Tissue Fibers, Increase New Cell Growth & More With Something Called “TB-500”.

Articles, Supplements

Last month, in the article “How To Use BPC-157: A Complete Dummies Guide To Healing The Body Like Wolverine“, I introduced the little-known concept of using BPC-157 peptide self-injections and oral BPC-157 peptide consumption (currently completely legal and not banned by sporting organizations) for everything from rapidly healing leaky gut to fixing tendon, ligament and muscle injuries.

In that article, you learned how to order BPC-157, how to “reconstitute” BPC-157 to make it biologically active, how to inject BPC-157 either intramuscularly or subcutaneously, how to take it orally, and BPC-157 research and side effects. I’d highly recommend you review that article prior to reading this one.

Since writing about BPC-157, I’ve taken an even deeper dive into the underground world of peptides, and found another similar peptide to BPC-157: something called “TB-500“, also known as Thymosin Beta 4.

TB-500 is a synthetic peptide that has been directly linked to impressive extremely enhanced recovery times for muscle and more. It plays a vital role in building new blood vessels, new muscle tissue fibers, new cell migration and new blood cell reproduction.

TB-500 acts a bit differently (and in some cases, more effectively and quickly) than BPC-157 and in today’s article, you’re going to discover exactly what TB-500 is, how it works, how to use it, and any and all pre-cautions and side effects you should know about.

A warning: unlike BPC-157, TB-500 is absolutely, 100% banned by WADA and most other global sporting organization both in-competition and out-of-competition. You should NOT use this if you are competing in any such sanctioned sport as it definitely falls under the banned category of “Peptide Hormones, Growth Factors, Related Substances and Mimetics (S2)”.

What is TB-500?

TB-500, or Thymosin Beta 4, is a peptide that naturally occurs in the human body and in animal bodies, and, since it is mostly sold for research purposes and veterinary use, is typically implemented in clinical trials in horses.

Thymosins were discovered in the mid 1960’s, when Allan Goldstein from the Laboratory of Abraham White at the Albert Einstein College of Medicine in New York studied the role of the thymus in development of the vertebrate immune system. Since then, Dr. Goldstein founded a company that creates thymosin alpha 1 for the purpose of increasing immune cell activity, and thymosin beta 4 (TB-500) to promote wound repair and healing.

TB-500 has been used extensively for race horses to prevent adhesions from forming, although it is not a prescription veterinary drug. It’s an injectable peptide with limited human use. Mostly, it’s limited to humans who like to experiment, although reports of human use of thymosin dates back as far as 1974 – when a young girl became the first person to receive injections of thymosin because she was diagnosed without a functioning thymus gland.

TB-500 has been shown to offer many of the same effects of growth hormone (GH), including:

-Increasing strength through muscle growth
-Improving endurance
-Speeding up the healing process for wounds
-Reducing acute/chronic pain and/or inflammation
-Increasing flexibility
-Increasing hair growth

As you learned in the previous article on BPC-157, peptides are two or more amino acids linked together in a chain, and TB-500 is a simply a short peptide fragment of an actual hormone – a hormone called “Thymosin Beta-4”.

TB-500 and Thymosin Beta-4 are not exactly the same, although you’ll often see the two names used interchangeably in the peptide world (AKA broscience bodybuilding forums).  It’s much harder to get your hands on true Thymosin Beta-4, whether for research use, equine enhancement, athletic performance enhancement or bodybuilding. But TB-500’s peptide sequence shares most of the properties of Thymosin Beta-4, and it’s more economical to produce, thus easier to find.

Just in case you care about the specifics or you really, really miss high school chemistry class, you can dig into the molecular formula of TB-500 below. It is C212H350N56O78S and has an amino acid sequence of the following



So, how does this stuff work?

The main functionality of TB500 hinges on the ability to upregulate cell building proteins such as actin, which is a protein that forms (together with myosin) the contractile filaments of muscle cells, and is also involved in motion and metabolism in many other types of cells.. Upregulation of actin allows TB500 to promote healing, cell growth, cell migration and cell proliferation. This not only helps build new blood vessel pathways but also upregulates the type of “good” inflammation that is directly correlated with faster wound healing.

Due to its molecular structure and low molecular weight, TB-500 is very versatile, mobile and possesses the ability to travel long distances through tissues. This means that when targeting injured areas (chronic or acute), TB-500 has the ability to circulate through the body and “find” those areas of injury in order to enhance the healing or growth process. Many users have also noted the added benefits of improved flexibility, reduced inflammation in tendons, re-growth of lost hair, and darkening of grayed hair.

Currently, studies are also being conducted on the ability of TB-500 to heal damaged heart tissue, including “athlete’s heart”, also known as ventricular hypertrophy.

In the past, TB-500 has been used extensively for race horses to prevent muscular adhesions and injuries from forming, although it is not a prescription veterinary drug, and MedivetEquine reports that TB-500 offers a variety of benefits to all mammals, regardless of size, including:

In the majority of humans who experiment with TB-500 injections, TB-500 is most often used for acute injuries or wounds that would heal slow (when you need them to heal fast), or for more chronic injuries where the healing doesn’t seem to be happening.

Where to Get TB-500

You can find TB-500 (often sold under the name Thymosin Beta 4) on several peptide supplier websites. These websites can only legally sell the peptides for research purposes. For example:

  • Nord-Sci sells Thymosin Beta 4 for $79.99 for a 5mg bottle. (Use code BGF20 for 20% off)

When you get your TB-500, it will come in a powder form. Just like BPC-157, you will need to “reconstitute” it by adding bacteriostatic water. Go back and read my article on BPC-157 to get access to a peptide calculator that will help you with the mixing/dosage math. Once your TB-500 is properly mixed, you then draw the dose into an insulin syringe, and inject it intramuscularly, subcutaneously, or intravenously (according to your preference).

Supplies needed for TB-500 injection:




Steps for Mixing TB-500:

  1. Take the lids off both your bacteriostatic water and TB-500 containers.
  2. Rub the alcohol swab along the rubber stopper on the TB-500 container, and the top of the bacteriostatic water vial and allow each to air dry.
  3. Fill the insulin syringe with bacteriostatic water and slowly and carefully inject the syringe of water into the 5mg bottle of TB-500 – being careful to spray the water onto the sides of the container rather than directly into the powder. If you do this three times, you will nearly fill the 5mg bottle of TB-500.
  4. Your TB-500 is now reconstituted. You will want to keep it in the refrigerator or freezer to preserve it until you’re ready to use it.

Do not let your mixed TB-500 sit at room temperature or in the light or it will go bad. To ensure the highest quality, it needs to be kept out of direct light and at refrigerated or frozen temperatures.

When drawing TB-500 into syringes for injection, turn the bottle upside down slowly and draw the liquid into the syringe smoothly and slowly. When injecting, do so with a smooth, slow motion as well. Peptides are fragile and too much mixing and jostling of the container can damage or reduce the effectiveness of your product.

How to Inject TB-500

TB-500 can be delivered through subcutaneous, intramuscular, or intravenous injections.

Before using any of these methods, use a fresh alcohol swab to clean the rubber stopper of your TB-500 bottle and the area of injection. This will minimize your risks for bacteria and contamination.

Subcutaneous injections – you simply pinch an area of skin and push the needle through it. Tip: you should inject an area of your body near your actual injury.

Intramuscular injections – these are harder than subcutaneous injections as instead of simply inserting the needle under the skin, the needle must be “stabbed” into the muscle as close to the area you are experiencing pain or injury as possible.

Intravenous injection – the needle is inserted directly into the vein, usually on the wrist, elbow, or back of the hand. This one is pretty tough, and I don’t recommend unless you have medical supervision or really know what you’re doing.

After injecting TB-500, massage the area of injection for about a minute to help work the TB-500 into the tissues and improve the absorption and effectiveness.

The most common dose of TB-500/Thymosin Beta 4 is based on your body weight. For a 200-pound person, the dosage recommendation is about 7.66mg per week for six weeks. This is derived by calculating the human dose based on the recommended dosage of TB-500 for greyhounds (5 mg) according to MediVet (the TB-500 manufacturer).


At the risk of sending you down a broscience rabbit hole, here’s a link to a bodybuilding forum discussion that delves into TB-500 dosage in more detail, along with some practical user experiences.

Side Effects and Risks Of TB-500

You should know that there have been some conflicting research studies about this stuff when it comes to cancer. Some studies suggest that it may contribute to the growth of existing cancer cells, while further data suggests it may inhibit cancer.

Doctors have noticed cancer patients have a higher amount of Thymosin in the affected tissues than other people. So in the early stages of research, doctors assumed that this meant Thymosin may cause cancer. After more research was conducted, it was discovered that the main action of Thymosin Beta 4 was to produce new white blood cells – so its presence in the body in the areas affected by cancer was likely not a cause of the cancer, but instead, a matter of “showing up” in the body where cancer lived to help the body mount an immune system response.

But like most peptides on the market, TB-500 has limited long term studies involving human use. Although I haven’t personally used TB-500 (I can’t, since I compete in WADA sanctioned sports like triathlon and obstacle course racing), from what I’ve seen and heard from bodybuilders and athletes using the peptide, the primary side effect is a temporary sense of lethargy. Also, some people report getting a head rush when injecting TB-500, but report this head rush goes away a few minutes after injecting.


Here’s the deal: peptides are the wild, wild west of supplementation.

Many are illegal for sanctioned sporting purposes, so do your research (I recommend for this).

Many do not have long term safety studies in humans, but decent track records in animals.

Proceed at your own risk.

But when it comes to healing injuries fast, healing the gut, growing new muscle faster, or getting any of the other benefits I mentioned in this article, it may be worth looking into peptides such as TB-500 or BPC-157.

    Hello Ben,

    isit possible to use acetic acid water to mix TB500 or PBC157?

    I bought it instead of BW



    1. Ben Greenfield says:

      I wouldn't. Can't vouch for that water…only sterile bacteriostatic.

  2. Pete says:

    Hi Ben or other readers

    How stupid would it be to try and take this stuff in my suitcase from the UK to the US?

    Since it is not illegal to buy and own it, would I be ok? Or am I setting myself up for unnecessary problems?

  3. Nick says:

    Have you heard of any improvements to spinal disc hydration levels through using TB-500 or BPC-157? So for a dehydrated and bulging but not burst disc to gain height through stimulated repair through peptide use?

  4. Joe says:

    Hey mate, I’m getting a shoulder reconstrcution in about 2 weeks. Do you think that TB-500 and BPC-157 would help heal something as complex as this. Or do you think that stacking something like GHRP-6 and CJC-1295 would work better because this would assist in muscle growth and strength gains of surrounding muscles etc. Also if chose to use peptides when do you think I should start using them, I will be in a sling for 6weeks after surgery with only passive movements.

  5. Kimberly Harper says:

    Hi Ben

    I was in a bad accident 5 years ago and was feeling better until my Dr. gave me levaquin which damages your mitochondria, gut, tendons And ligaments. I was going to order BPC 157 but see where you think TB500 is stronger. Do you know if it shows up on an employee drug test as i get tested occasionally? Also, your thoughts on fragment 176-191, a friend of mine uses it and suggested it for me. I understand you’re not a Dr, but just looking for your personal opinion. Thank you

    1. Yep, both will show up on a drug test but both also are out of your system after about 48 hours…

      1. Justin says:

        You think bpc 157 and tb 500 would show up on a employee drug screen? What drug would they show up as? im curious to know. To my knowledge a 10 panel test is not going to show peptides.

  6. Joe says:

    Just to be clear, you’re saying a standard dose for 200 lb. person would be 7.66mg, which is a little more than one 5mg bottle a week, correct?

    Also, did you use tb500 for yourself? If so, when did you see results? Which did you like better, the tb or the bpc?

    1. No, but i have used BPC-157. TB is more powerful. And you are approximately correct on dosage, yes.

  7. john says:

    Hey All, it seems the BPC-157 and AOD-9604 is a very effective and Safe combo….

  8. Jon Snow says:

    So I’m still dumb 5mg vial will get you how many doses when reconstituted with 2.5 ml of bac water?

  9. Hi Ben. Have a groin problem which I have had for years and it just won’t go away it’s not a hernia or osteitis pubis I had an MRI and the specialist said they wouldn’t operate. I can still play sport but I’m just less agile and slower than normal and it takes a few days for the groin pain to go away after sport. Would tb500 help to heal it or would bpc157 or something else be better? Thanks :)

  10. Lenora Holzapfel says:

    In 2015 I found my self bed ridden for 8 weeks with an issue all the doctors I had been to we’re unable to diagnose. I discovered, after much research, that what I was suffering from was damaged facia in my left and right gluteus muscles, which left me unable to do anything. I was in excruciating pain and couldn’t do anything except lay in bed on my back. Then my husband found TB 500. Initially I was against using it but after deteriorating to the point of being bed ridden I broke down and ordered some. As soon as I received it my husband injected me in the gluteus muscle. Within 30 minutes I started getting relief from the TB-500, within 8 weeks I was out of bed and the pain was gone! It healed the damaged fascia covering the gluteus. If I had not done this I don’t know where I would be today. For me, TB-500 was a life saver and if I had to I would use it again. I have suffered no side affects then or now.

    1. Thanks for sharing this experience. I am glad you were able to find something that worked.

    Beware : “Thymosin β4 induces invasion and migration of human colorectal cancer cells through the ILK/AKT/β-catenin signaling pathway”

    1. Raiderberg says:

      John why do you say beware?

      Thymosin beta4 regulates migration of colon cancer cells by a pathway involving interaction with Ku80.

      The results of the below article state article state: “..and is a potential target for cancer treatment.”

      These results suggest that Tβ4 is an important regulator of the ILK/AKT/β-catenin/Integrin signaling cascade to induce cell invasion and migration in colorectal cancer cells, and is a potential target for cancer treatment.

  12. Ferdi says:

    If u had a flexor tendonitis in your finger… What would u use? TB 500 or Bpc 157?


    1. I’d stack the regime because I feel they both pose significant benefits!

  13. Dee says:

    Ben!.. quick question. I am. Musician looking to prActise as many hours in a day as physically possible, as sore and inflamed muscles and tendons from repetitive movement is the only problem.. what should I take and what amounts?… can I take it indefinitely? Where to buy? (From Canada). PleaSe help asap. Forward to email please..Thanks!…

  14. Brad says:

    Hi Ben, great article!!. I have wrist tendinitis and can’t lift anymore it’s driving me crazy. For TB 500 what method of use do you recommend? Intervenes etc.

  15. Katherine Watkins says:

    Which out of BP157 or TB500 (or a combination of both) would you think would be better for a case of De Quervain’s thumb tenosynovitis?

    1. I think the combination of both would be the ultimate approach.

  16. Brooke says:

    I am not sure if my original question posted…I was wondering if I could use TB-500 to regenerate thyroid tissue? My endocrinologist said that my Hashimoto’s Thyroiditis has almost completely destroyed my thyroid. If yes, then where do I inject?? Additionally, I was wonder if the BPC-157 would have any benefits on thyroid as I plan to take orally for leaky gut/digestive issues.

  17. Brooke says:

    Hi Ben,

    I’ve tried researching this on my own but haven’t been able to find much. I have Hashimoto’s Thyroiditis & my endocrinologist says I barely have any thyroid left. Would TB-500 help regenerate new thyroid growth & if so where would I inject it?? I plan on taking this along with the BPC-157 (orally) for gut inflammation to see if it can repair leaky gut & digestive issues. Thoughts?

  18. Bernie says:

    I wonder if this would be effective if applied transdermally. ie. in my case, applied to skin in the vicinity of an old and troublesome shoulder injury.

  19. Martin says:

    Hi Ben,

    Do you think it’s a good idea to use both TB500 and BPC–157 at the same time.

    Also do you have any idea of TB500’s half life?

  20. Lily says:

    I am interested in your product.

    1. Do you have any questions I can help you with?

  21. Jo Boy says:

    Would TB-500 help in healing peripheral nerves that have been injured for many years? I have a 6-year old ulnar nerve injury which has barely healed since the initial injury. Thanks.

    1. I am not a doctor and nothing I say should be taken as medical advice. Please talk to a licensed physician about this. There is plenty of evidence that this can be used to help the nerves, yes.

  22. Rob says:

    When’s the best time to take this , I’m guessing before bed since most muscle growth happens while resting/ sleeping

    1. Timing doesn't seem to be that important as the half-life in the bloodstream is pretty long. Post workout is when a lot of people do this.

  23. Reggie Love says:

    Iam recovering from a ruptured quad tendon i have read your articles and have decided to try tb 500 I am looking for a reliable web site to purchase the product and would like to ask if I m using 5mg a week what number woud that be on a insulin syringe, thanks for your help

    1. If you read through this article, you'll find all your answers!

  24. James says:

    Should I be using this along with some Curcumin and hot/cold baths?

    1. Not necessary as it can blunt hormetic response!

      1. Raiderberg says:


        Thank you for all of the helpful information. 3 failed shoulder surgeries and a lifetime of not caring about my body has me in pain every day. I started BPC 15 and Beta4. Definitely seeing improvement, but still in pain even when I type. I consumed about 15mg of each over a two week period. Moving to week three of BPC 157

        I am thinking about adding IBF to the regime.

        I also visit the Chiropactor weekly, Cryotherapy daily, and started Structural Integration today.

        Do you think Cryotherapy is restricting my cell growth? It has really helped with managing the inflammation that builds up in my shoulder every day.

        1. Cryotherapy when done in excess can indeed limit healing, so use that in early stages of healing, then back off. Heat and electrostimulation are better at that point. look into this, for example:

  25. Stephen says:

    Hi, I was wondering the protocol for injection, if I was for example doing 5mg a week, would it be 1 dose of 5mg once a week or 5 doses of 1mg per day

  26. Jim says:

    My wife has suffered from debilitating leg cramps for years, usually nocturnal. We have spent much money and time trying to find a cure, including every type of magnesium supplement we could find. Nothing has worked. We’ve also tried MSM and DMSO. Sometimes the cramps are in her calves, sometimes her thighs, sometimes her back and even her toes. Sometimes several muscles cramp at once. She has a high tolerance for pain, but these cramps leave her sobbing. I have purchased TB-500 and received it today. Does your research offer any hope that this could help eliminate her muscle spasms?

  27. Fred says:

    When taking BPC or TB orally what in erase in dosage is required to equal your protocol for injection. How many my per week/day.

    Thanks in advance.

    1. Hey Fred, you'll find all the dosing info here:… let me know if you have any further questions.

    2. bub says:

      why would you take a peptide orally? It’ll be digested, that’s why you need to inject.

  28. Fred says:

    If using TB for 4-6 months to help healing of an injury. How long will it be before being able to test clean in a blood test. Thanks.

    1. I would give yourself at least 48 hours or more… For it to get out of the bloodstream…

  29. dirk says:

    Hi Ben,

    I have orderet BPC157 and Thymosin ß4 (peptides warehouse) in order to hopefully help a painful knee. It’s mcl related, and quads, calfs that are too tight… But it is something muscular or tendons… I’m planning on dosing BPC @ 500mcg/day and TB4 @ 2 x 2mg/week… You think this is a good setup?


    1. That looks like a pretty good setup to me.

  30. Donnie says:

    I’ve had several back surgeries. I have cages and screws in my back. Which of these would help the recovery of my coresume and lower back? BPC 157 or TB 500?

    1. I am not a doctor and this is not to be taken, interpreted or construed as medical advice. Please talk with a licensed medical professional about this. These are just my own personal thoughts and not a prescription or a diagnosis or any form of health care whatsoever. However, both could be efficacious. TB tends to be more powerful than BPC…

  31. Craig says:

    Hi Ben.. I have an old hip fracture that went un noticed.. which lead to osteoarthritis.. hip impingement and a laberal tear.. also have wear and tear on my left hand, 3rd metacarpol is painful and weak.. seems like my tendon is not in line..

    Can I inject TB500 into my damaged hand ?

    Kind regards


  32. Russell Stumpf says:

    I bought this TB 500 but it says it’s 44 amino acids? Is there a difference? Link below.

    1. I will only vouch for the TB-500 I talk about in the article above. It is the stuff that I've actually vetted.

  33. B Patterson says:

    Can I take TB-500 , with vielight 810?

    Ur so cool Ben.

        1. A subcutaneous injection near the injury site may work.

          I am not a doctor and this is not to be taken, interpreted or construed as medical advice. Please talk with a licensed medical professional about this. These are just my own personal thoughts and not a prescription or a diagnosis or any form of health care whatsoever.

    1. Hamish says:

      Whats the half-life of it? How long after is it detectable in urine and blood?

      1. It will stay detectable for anywhere from 2 to 4 days after injecting…

  34. Sean says:

    Is this effective taken orally? And is it safe to take bacwater with this orally? Thanks

    1. Yes, but it's going to be more effective if injected.

  35. Kim says:

    Hi Ben,

    I have bee suffering from severe symptoms of post concussion syndrome for several.months after a car accident. The use of TB500 has been the only trratment ease my symptoms and give me my life back. I ceased use last week after 3 weeks and had reoccuring concussion symptoms. As such? I recommenced injections as of last night. Have you read much about the impact of TB500 on brain injury as I’d love to know if more prolonged use would have a permanent impact/remedy for me? Thanks for your time and interest.

    1. Kerry says:

      Hello Kim

      I read your comment regarding concussion symptoms and wanted to offer something that you may want to research further.

      I don’t recall any literature (research or anecdotal) suggesting that TB 500 showed efficacy with regard to repair of brain tissue. I have however read anecdotal comments regarding N-Acetyl Semax Amidate with regard to increase in BDNF (Brain-derived neurotrophic factor) and the growth of new neurons. I am currently testing N-Acetyl Semax Amidate for its nootropic properties however I have read post in which people suggest that it is “healing” brain damage.

      I am simply offering this as an area of research that you may find of interest.


  36. AMANDAYC says:

    Hi Ben, so how much time do I have to use up a vial of tb 500? How many days if I keep it refrigerated? Thanks!

    1. Most research shows TB-500 to stay good unrefrigerated for month or two if not reconstituted. Once reconstituted, it should be refrigerated and used within one week. That is the primary reason this stuff comes in such low dosages (e.g. 5mg for an average one week of dosing and 2 mg for an average maintenance dose).

  37. MandiYC says:

    Hi Ben, so in your non-medical opinion, which is better ( bpc 157 or tb 500) for reducing inflammation in the joints? I’m considering taking it orally, 250mcg daily for 30 days. Thanks for your feedback.

    1. I'm a bigger fan of TB for that…

  38. Dave says:

    Hey Ben,

    Can I combine BPC157 and TB500 in the same syringe? I scanned through and didn’t see this question. Sorry if I missed it.



  39. MYuen says:

    Hi Ben,

    I had tennis elbow on both arms for over 3 years now. Had one surgery on the R, countless PRPs, and a stem cell treatment on both but still to no avail. Pain on the L never eased up and I just had my 3rd PRP booster injections yesterday after having my stem cells 2 months ago. So can you tell me if BPC 157 or TB 500 better suits my situation. Many thanks!

    1. Charlie Kent says:

      Dude I am in the exact same boat though I also have chrnic patella tendonitis as well unfortunately. I went on a cycle of thymosin beta 4 with CJC but I did not see any real improvements. I have not tried BPC 157, though if i do I will continue with eccentric exercises to hope the collagen heals

  40. jerry says:

    Hi question is this, I have a 9 year old german shepard..his back end is all of a sudden weak, where he will fall over,like he can’t hold himself up, I can see extreme weaknes inhis hide quarter.The vet has taken many x-rays and blood work, but all comes back perfect.Do you think this pepetide would help my dog?..he is 101 pounds, extremely strong, Walking is his issue, he can run like the wind, then he can fall over.Any help would be greatly appreciated.

    1. Hey Jerry, I am not a doctor and nothing I say should be taken as medical advice. If it were me yes, I would try it.

  41. Sean says:

    How significant is the strength and endurance benefits from tb500? Ive seen many logs raving about the healing effects but havent seen many mentioning performance benefits

    1. More fat loss/muscle gain benefits IMO.

  42. Ryan says:

    I have done my research related to this, I am thinking about ordering TB-500…I have a few questions to ask before ordering, I am a volleyball player and stopped playing for a while to let it rest and in process of healing. I have A SLAP tear is an injury to the labrum of the shoulder. Should I use TB-500 for shoulder so it can increase muscle growth? I would be interested on your take of how to do the injections there.

    Any thoughts/opinions or recommendations are greatly appreciated! Thanks for your help and this info :)

    1. I am not a doctor and nothing I say should be taken as medical advice. If it were me, I would try TB500, and to inject simply get as close to the injury site as possible. If you want to go into detail feel free to book a consult at <a href="” target=”_blank”> and choose 20 or 60 minutes and we'll get you scheduled for a Skype consult.

    Wondering which would be more affective for ligament and tendon tears TB500 or BP175 I’m currently dealing with a Scapholunate ligament tear.

    1. I am not a doctor and nothing I say should be taken as medical advice. I would go for TB500 as long as you know its a banned substance.

  44. Michael says:

    I notice unlike BPC-157, TB-500 usually doesn’t list ligaments/tendons in the list of benefits (you only mention reducing tendon inflammation). Would it be accurate to say BPC-157 is better for joints/ligaments/tendon/cartilage while TB-500 is better for more vascular muscles/skin/etc?

    I’m curious why you say TB-500 is stronger, the studies showing BPC-157 healing severed ligaments/tendons seems way more radical and impressive than TB-500’s merely lowering tendon inflammation, and for most people connective tissue injuries are the much more problematic issue.

    >TB-500 is a synthetic peptide that has been directly linked to impressive extremely enhanced recovery times for muscle and more. It plays a vital role in building new blood vessels, new muscle tissue fibers, new cell migration and new blood cell reproduction.

    1. That's an accurate approximation, yep.

    Hi Ben

    Ive been struggling with my left brachialis and so after listening to a podcast in which you mentioned BPC-157 I tried it out. I was hoping for a miracle cure, which I did not get. However, I believe it certainly helped a lot. I am considering a second round. But the peptide rabbit hole is certainly interesting and I am most keen to try some others. But I would like to see if you have some advise for me on another topic. After having listened to your podcast with Dr Gains I thought that either you or Dr Gains may be able to at least point me in the right direction. My wife suffers from a condition called Pelvic Vein Congestion which causes her a lot of pain. From what I understand, she has a seemingly unnatural mass of veins around her uterus which may also suffer from a “valve” type problem in which blood can potentially run in the opposite direction and pool in locations which causes pain. She has been to doctors which offer invasive solutions with unattractive success rates. I have been searching for other cures, but the only thing that I found (supplement with Diosmin and Hisperidan) had some psychological effects. Any thoughts?

  46. David Whitney says:

    Ben, what about using this or bpc 157 for the SI joint? Mine has been acting up for years. A lot if cracking and popping. It’s definitely a weak link. But it just seems like a scarey spot to go IM.

    1. I am not a doctor and this is not to be taken, interpreted or construed as medical advice. Please talk with a licensed medical professional about this. These are just my own personal thoughts and not a prescription or a diagnosis or any form of health care whatsoever.

      If I were you, for the SI joint I would do this exact program: – that's why i wrote it!

  47. Tiffany Palmer says:

    Hey Ben! Thank you for all of your awesome content. I am wondering if you are familiar with Medivet Equine’s TB-1000 which they market to be twice as concentrated and potent as TB-500? I can find no clinical research to support this claim, and am wondering your thoughts/opinion. Thanks so much!

    1. I am not and have not used it yet but suspect it is very similar to TB500…

  48. nasa says:

    do you have to take bpc- 500 on a empty stomach ??? or you have to have carbs in your body?

    1. Nope, you can take it on full or empty stomach although because it is a gastric peptide, empty stomach may be better.

  49. Simon says:

    As BPC 157 and TB500 seem to have different mechanisms of actions could it make sense to take them together or are there any contraindications you’re aware of?

    1. I would say save your money, take one or the other, and if you HAD to choose and it is legal for your sport, TB-500.

  50. Charlie says:

    Hi Ben, has your post on IGF-1 LR3 & DES been released?

    Kind Regards,


  51. Lukas says:

    Hi Ben what is your advice for how frequent to inject and length of time to trial Thymosin and see results?


    1. It's all right there in the article…

  52. Chris says:

    Hello, I have started taking bpc157 and tb500 last week to help with tendinitis of the patellar and an SI injury. Wasn’t expecting much for the SI but I can say something is definitely working. Both are feeling much better and I’m only just over a week in.

    I was kind of scared because I ran across some threads that said TB500 leads to cancer or promotion of benign tumors…most of these were at least 4-5 years old though and it seems there are countless logs online all with good experiences. Nonetheless I was still worried so I did some more research and came across a pharmaceutical company in the US doing clinical trials for thymosin beta 4 to help with dry eye syndrome. I have attached some links. This makes me feel much safer but if you have any more insight I’d really appreciate it.

  53. Alfonso says:

    Ben, i remember you saying you had sprained your ankle during one of the spartan and you used this as a recovery. How exactly did you inject into the ankle?

    1. Subcutaneously around the medial malleolus.

  54. John says:

    Ben, just to make sure I’m understanding the maths correctly and not going crazy on the dose. Based upon the recommended dose of 7.66mg / week, it would be expected to use up 1.5 vials of this stuff per week for a 200 pound person?

    Alos, based on what you read, do you have any thoughts about how best to do this? One shot once a week or a set number of days apart?

    1. Hey John, all your questions can be answered by reading through this:… and checking out the peptides calculator here:

  55. Dominick Maron says:

    Hi Ben,
    This may be an odd question. But would this be good to inject or spray on those that have undergone hair transplants in the first month of surgery. Fue microscars. I see you mention it improves hair growth and blood flow. both which basically what rogaine claims to do. Surely this would benefit new transplanted hair follicles in taking and holding? Interested in your thoughts in the matter.


    1. I haven't seen actual research on hair growth, but theoretically, this could indeed accelerate capillarization and blood flow!

  56. Jb says:

    Hey Ben,
    What is the equation you would used to determine how much TB 500 to use per kg? Wondering how many 5ml vials I need to purchase to treat bilateral anterior shoulder pain.
    Thx, Jb

    1. Read this first, everything you need to know is in here:

  58. Charlie Cross says:

    Hi Ben!

    Have you had any personal experience or know anyone who has used IGF-1 LR3 & DES?

    Thank you for all the informative work you share!


    1. I have an upcoming post on this one! Stay tuned!

      1. Charlie Cross says:

        Perfect ! Are you able to email me once it is up?

        Kind Regards

        1. I can't sorry! You just need to stay tuned!

  59. Bob says:

    Ben, how would this be for hip labral tear?

    1. I am not a doctor and nothing I say should be taken as medical advice. I would definitely give it a go. Let me know if you have any more questions.

  60. Travis says:

    Can I take TB500 with SARMS? If so, which stack would you recommend for lean muscle and strength? I also have some tendon pain on the inside of my elbow, thinking TB500 could help.


  61. Johan says:

    Is it possible to take TB500 oral as BC-157 (oral bioavailability)?

    1. Yep, same as BPC you can take it orally and it will work systemically.

  62. James says:

    Hi Ben and thanks for all the great information! Just wondering if you see any reason that I shouldn’t start a TB500 cycle almost immediately after a BPC157 cycle. It’s only been a few days after I’ve finished my BPC157 (with some “success”) but I’m anxious to being the TB500. Thoughts? Thanks!

    1. You can do it, but I'd recommend taking both at once then cycling off both at once.

  63. Lindsay Lee says:

    This is amazing! The use of the TB-500 and Thymosin Beta 4 for humans are limited and it can increase muscle growth, improve endurance and most of all can speed up the healing process of wounds. Essentially, peptides are small proteins that can help to boost the naturally occurring hormones within your body, to help you achieve better results.

  64. Richard says:


    My wife is an elite athlete who had hip surgery for a torn labrum with impingement. Recovery is super slow and testing is not a current concern… Any suggestions for site and frequency of injection?

    1. I am not a doctor and nothing I say should be taken as medical advice. If you have a read through the article, I would suggest following the recommendations there. If you want to go into detail book a consult at <a href="” target=”_blank”> and choose 20 or 60 minutes and we'll get you scheduled.

  65. Edmo says:

    There is a site in Australia selling TB-500 reconstituted in 15ml vials. They say to go with 25 units daily for loading. This would mean one month from the same vile. Are you saying that it would be”bad” after 8 days?

    1. I can ONLY vouch for the TB-500 source I have listed here (peptides warehouse)…and the loading scheme I recommend above. That is *all* I ill vouch for! Keep any you don't want going bad in the freezer btw.

  66. Tanveer says:

    Hey ben , great article.

    Would combining BPC-157 with TB-500 be same as combining it with MK-677 or any other GH increaser for recovery ? Or is the BPC-157 + TB-500 combo the way to go ?


  67. Brian palme says:

    Can tb 500 be taken orally

  68. matthew perry says:

    Hey Ben

    Can you pre-fill syringes with tb500 and put in the freezer until use. Do you have experience freezing this peptide and using it later? I heard once tb-500 has been reconstituted, you have to use it up in 8 days before it goes bad!

    1. Theoretically yes, but you do need to use relatively quickly after reconstitution so if it were me I'd reconstitute "fresh" batch.

  69. Luke Voigt says:

    Hey Ben,

    Is there any reason you didn’t list Blue Sky Peptides with your sources for this one?

    Wondering if you discovered something about quality since the previous BP-157 post.


    1. I'm pretty sure you can get this from blue sky peptides too but I didn't check there. Their peptides are good though.

  70. Dan says:

    Ok Ben ordered the stuff as you suggested. 3 bottles. Going to give it a shot on my elbows which have a bit of tendinitis from doing lots of ring and bar work.

    Do I try and inject it right into the tendon?

    How long does the mix last?

    Also strained my back a bit would this work for that as well? Inject it into the lower back muscle?

    Any advice would be aprciated. I do believe you used it on your elbow tendinitis as well so I would be interested on your take of how to do the injections there.


    1. For the elbow – subcutaneously, exactly over the area of pain. Pinch the skin and inject away. Best to book a consult for the rest of the questions and we'll go over it there. <a href="” target=”_blank”> and choose 20 or 60 minutes.

      1. Dan says:

        Ok Ben. Thanks. Started the TB 500 for my elbows. Got the 5mg of TB 500 and reconstituted it with 3 cc/ml. of water (3 syringes full) Just about filled the file. Now based on injecting just under .1 cc/ml or just under 10 (8) units for a dose of around 250. How long did that vial last you? Seems like there is a lot left and the amount injected is small. Is my dose and math right?

    2. Boris says:

      Should I use TB-500 or BPC-157 for an Achilles. I recently tore it and was wondering if any of these products could speed up my recovery?

      1. Either would work but if you're not competing in sanctioned sports then TB500 is more powerful.

  71. Tim says:

    Peptides seem different than anabolics /hgh in the fact that (i’m asking) they don’t shut down or disregulate any of your bodies natural productions /processes or make you feel “weak” it different after stopping them correct?

    1. That is indeed correct.

  72. Brian says:


    I’ve recently been diagnosed with osteoarthritis in my right knee, with significant cartilage damage. Would either TB-500 or BPC-157 be worth trying in this situation?

    1. I am not a doctor and nothing I say should be taken as medical advice, and yes it's worth trying.

  73. I’m always interested in learning about better supplements for my health. I’ve heard a lot of good things about peptides, but this was the first time I’ve read about TB-500 in particular. It sounds like it can have a major impact on helping you recover from injuries, which is a huge deal in today’s world. I may need to look into it some more before actually buying it, but thank you so much for taking the time to explain it!

  74. Kevin Brown says:

    I have taken BPC-157 in conjunction with TB-500 after reading about someone’s experience. I used the BPC-157 at an injury/inflammation site in my shoulder. I have a pain that came out of nowhere and has prevented me from doing bench presses mainly, and shoulder presses. I also got pain when I did external rotation of my shoulder. The BPC-157 gave me good results at 250 mcg twice daily intramuscularly. The pain is not completely gone but it has definitely lessened in severity. I don’t get any pain with a reverse grip press so I have been doing those with light weight and I can now do shoulder presses. BPC-157 really blew me away on how quickly it improved my gut status. For me it only took 4 days of orally dosing with 250 mcg. So I did both the oral and intramuscular daily for a month. Two weeks into the BPC-157 I ordered TB-500 and did 1mg per week subq in my thigh because I didn’t know about injecting intramuscularly at the injury site.

    With the TB-500 it seems that pain was reduced even more in my shoulder and it appears that I recovered much faster from my workouts. I took the TB-500 on rest days. I have two more 1mg doses of TB-500 and I am going to site inject intramuscularly to the shoulder to see what happens. Then I will stop taking both for a month to see how things work out. Hopefully I won’t need them again.

    Thanks for the info Ben!

  75. Natalie says:

    I have an upcoming surgery and their will be a very long incision basically from my knee to ankle on both legs. Do you feel this would help with healing the would and potential scar tissue. Is TB 500 or BPC a better choice or both??

    1. Honestly either could work. I am not a doctor and nothing I say should be taken as medical advice. TB-500 is probably a bit more powerful.

  76. Brett says:

    Hi Ben, I have been using TB-500 for minor injury repair assistance for more than 2 years. I have found it to be extremely effective for minor strains to calves, hamstring, shoulder etc. Luckily I have not had to try it for any major injuries. When I first used it I was blown away by how effectively it worked – even to the point that I began to doubt the seriousness of the original injury. When injured I dose at 5mg per week for four weeks then take at least four weeks break. The only side affect I have noticed is a little light headed feeling which passes pretty quickly. I am in my late 40’s and I train hard. TB-500 allows me to train through minor injuries which is great. Love your work

  77. Rich says:

    Does this peptide also help heal leaky gut like BPC-157?

  78. Peggy says:

    Would TB-500 or BPC-157 be helpful for broken bones with poor vascularity?

  79. Tom says:

    The above references demonstrate a relationship to cancer. Can you please provide references that substantiate your position that TB-500 presented with CA is not contributory. Many thanks.

      And drinking soy increases your risk of endometrial hyperplasia.

      The same arguments are seen with insulin, insulin growth factor (IGF), HGH, and anything that increases over expression and up regulation of androgenic receptors.

      I think it’s all about what your goals are as anything that isn’t organic and 100% natural is technically foreign to your body and has its side effects

    2. The research goes back and forth. I highly suspect that in a case of mitochondrial integrity – such as discussed in my recent podcast with Dr. David Minkoff on what really causes cancer – it is a nonissue. But that is just a hypothesis.

  80. joe benoit says:

    Hi..i had 3 major muscle tears(complete)..2 in shoulder and 1in bicep..they all needed surgery for reattachment.. ive done a 20 day round with 157 and believed it at 7 weeks post op and have about 5 month’s of recovery still to go.. thinking another round of 157..wondering if the TB500 might be a better option or stay with 157? As an athlete and top Spartan racer,im looking to speed up process by any %. Any thoughts/opinions or recommendations are greatly appreciated! Thanks for your help and this info :)

    1. If you are racing Spartans you can't take TB-500. So there's your answer!

    2. joe says:

      Spartan does not test.. And i missed this year due to this injury.. Judt want to know if the TB500 would be a good choice given my injury.. Will be 12 months before any racing.. Might not do Spartan either.. Just local stuff.. Thanks

      1. BPC-157 better choice for you I think if you are racing.

  81. joe says:

    hi..had three torn muscles between shoulder and bicep..all needed surgery for re attachment.. did a 20 day round of 157.. believed it helped..looking for a suggestion..another round or do you think the TB500 may be better? im at 7weeks of a 6-8month healing process. Thank for these articles and any insights-recommendations you may have.

  82. wendy ralfe says:

    Ben, are there other ways to heal faster/ recover faster from training, that dont involve injecting yourself? lol

  83. Pete says:

    Hi Ben, I am interested that you mention one of the effects as reduced inflammation in tendons. Have you come across anything to eliminate Dupuytren’s constricture, which is a disease of tendons in the hand, without surgery?

    I’m always interested in your research. Many Thanks, Pete

    1. I am not a doctor and nothing I say should be taken as medical advice. Probably the best resource for you would be to really focus on improving your tendon integrity and this article would be quite helpful for you with regards to that:

      1. Pete says:

        Thanks Ben, that has given me a couple of things to try.

  84. Francisco Aguiar says:

    Do you think this would be good for a fractured kneecap?

    1. I am not a doctor and nothing I say should be taken as medical advice. However, I have seen some studies that show that the anabolic effect may help with bone healing.

  85. Clinton Goodsoul says:

    BPC 157 for healing gut also has a good potential when taking as enema technically . For healing leaky gut etc . So that may be way to try it , should be very potent that way and has been done before. Did you have anny luck shuttint down leaky gut etc with oral administration Ben ? Lactulose / mannitol testing before after ? BLP?

    1. I don't have leaky gut so I couldn't tell you. But the anime idea is quite interesting. And you may want to look into this:
