In this 72nd episode of Ayık Kafa podcast, Dr. Esra Çavuşoğlu, PhD welcomes  a pro-natural athlete, biohacker, and bodybuilder Kris Gethin. Gethin traces his journey frommotocross racer to injury-driven weight-training convert, explains why he pursues extreme fitness without anabolic steroids, and shares how biohacking practices from daily ice baths to Faraday-lined clothing, help him keep his biological age at 26 despite being 50.

The conversation ranges from the science-backed macros he uses with clients to reversing long COVID induced testosterone drops, the mental edge of 100-rep sets, and why his supplement line Unmatched merges “healthspan” ingredients with sports-nutrition doses. Along the way he delivers pragmatic advice for anyone over 40 who wants to fend off sarcopenia, protect bone density, and stay metabolically resilient without sacrificing life quality.
