If you've seen the latest Netflix documentary on Bryan Johnson, you already know gene therapy is no longer the stuff of sci-fi. But is it the ultimate biohack… or a dangerous, unproven gamble?

Today, I'm joined by Bryan Johnson's gene therapist—Mac Davis. He's the founder of Minicircle, the company featured in the documentary, and he even appeared in it himself. 

Gene therapy isn't the future—it's happening right now. And the man behind one of the most controversial longevity experiments in biohacking is with me today.
