    Looking to try this ketamine and oxytocin stack before a massage. You talk about it in boundless some and I have also heard you talk about it in a previous podcast with Drew Canole. What are the recommended brands and what dosage for each?

    Ben….you got the gift! Ever consider being a preacher? My spirit has been inspired by the
    Journey you’ve been on…loving God & loving others and sharing it unashamedly with the world!
    BTW enjoyed your book Fit Soul.

  3. Rachael says:

    Thank you Ben and Matt for THE most beautiful podcasts I’ve listened to. I happened to be on my 4 mile trail walk in the woods this morning while listening to this. Ben, your testimony spoke to my heart and in no doubt has done the same for so many others who listened. Those who Really listened. Matt, I am looking forward to listening to your podcasts in the future and so excited to learn from you. I am totally loving your RA optics…I am with you Ben, as I lost a pair of my BLBs to one of my dogs and another pair got mangled in a snow blower last month (after leaving them on top of my car and blown off during a winter storm). Much love and respect to you both.

    I am über inspired by you Christian testimony Ben. In todays world I often feel alone in my faith. If today was just average for you, just think about how you effected me in such a positive way. Not many Christians inspire me…but you did. PS…Am I the only one?

    1. You are not alone, Rob. I concur that it can feel that way sometimes… But your Christian brothers are near. We have been quiet with our faith and don’t bring it to our office, gym, or into our community. But we can’t do this anymore. Our families, churches, offices, and communities need us to step up, share our story, and take the lead!

    I may have missed it. Does Matt have his own podcast? If so, what is it called and where can it be found?
