This episode covers:

A thoughtful, science-based conversation about peptides, designed specifically for the peptide-curious with Dr. Chris Renna. This isn’t a sales pitch or a “everyone should be on peptides” episode (I'm not!). It’s an honest conversation about where peptides may fit, and where foundational health still matters more.

Dr. Renna is a family physician who graduated from the University of Texas and earned his medical degree cum laude from the University of North Texas Health Science Center. Early in his career, he realized traditional medical training focused on diagnosing disease rather than creating true health, so in 1992, he founded LifeSpan Medicine, a personalized, prevention-focused practice built on concierge support and 24/7 access to care. With more than three decades dedicated to helping patients optimize their health, he’s become a nationally recognized leader in preventive medicine, as well as a published author and sought-after speaker.
