Mr. Benjamin Franklin Esgro has the unique honor of being our first guest in our episodes numbered in the 200’s, as well as being on for his fifth, or maybe sixth time? We aren’t sure, but we like to have the man on! I’m this episode, he’s once again crusading against potential charlatans in the supplement industry. If you remember last time, Ben joined us to discuss the lacking evidence of a mechanism of action behind turkesterone and today, he’s back to give us a dose of reality on paraxanthine. What is paraxanthine you might ask? Well if you haven’t already heard of it, it’s supposedly the next big thing in the stimulant, nootropic and pre workout world. But, while this supplement is interesting and may have specific utility, should we really expect something truly groundbreaking considering it’s a metabolite of caffeine? Join us as we ask Ben Esgro to find out.
