543: The New Rules of Men’s Health, Aging, and Performance | Josh Duhamel

What It Covers

Actor Josh Duhamel discusses cofounding Gatlin, a men's health company focused on testosterone replacement therapy, peptides, and longevity protocols, while sharing his personal journey from vanity-driven wellness to optimizing health span for his young children.

Key Questions Answered

• •Testosterone replacement therapy normalization: TRT restores testosterone to mid-twenties levels rather than creating super-physiologic doses for muscle building. Men often don't notice gradual decline until they experience the contrast of going off therapy, which reveals lost energy and motivation they'd adapted to over years.
• •Peptide injury recovery stack: The Wolverine stack combines four peptides including BPC-157 that target inflammation and injury sites, enabling recovery from chronic joint issues within one week. Athletes use these protocols to return from injuries faster than traditional timelines, with Josh experiencing relief from shoulder and Achilles problems.
• •Hot yoga for joint preservation: Starting hot yoga at age 43 literally fixed chronic back and knee problems that accumulated from decades of high-intensity training and sports. This practice proved more effective for joint health than continuing aggressive workout routines that caused injury-prone patterns throughout his thirties and forties.
• •Seventy-two hour fasting protocol: Gatlin organizes group fasts with 500 participants led by longevity expert Dr. Robert Lufkin, using daily Zoom calls to explain ketosis, autophagy, and zombie cell elimination. Group accountability makes extended fasting sustainable compared to solo attempts, improving adherence and education simultaneously.
• •Energy protection boundaries: Maintaining close relationships with friends from kindergarten while selectively engaging with new people prevents energy depletion from those who bring nothing to interactions. This becomes easier with age as caring less about external validation frees mental resources for meaningful connections and family priorities.
