In this power-packed episode, I sit down with longevity expert Dr. Elizabeth Yurth to dismantle popular biohacking trends and get down to the cellular root of aging. We dive deep into why mitochondrial dysfunction is often the culprit behind chronic fatigue—especially post-viral exposure—and Dr. Yurth walks me through her safety-first "replacement strategy" for cycling peptides like Thymosin Alpha-1, BPC-157, and GHK-Cu to restore what we naturally lose with age . We also have a critical conversation about the NAD+ craze, where I learn why filling the "bucket" with infusions might be fueling inflammation if we don't block the leaks first using compounds like Apigenin . Finally, we explore the game-changing role of plasmalogens for insulating our nerves against brain fog and why we are moving away from Metformin to protect our muscle gains .
