271: The Practical Peptide Guide for Recovery, Muscle, Fat Loss and Focus
The Kris Gethin Podcast
Peptides have gone mainstream, but the information around them is still a mess. One search brings up five different doses, four delivery methods, and stacks loaded with compounds you may not even need. Too many people copy the protocol, skip the reasoning, and only start asking questions when their energy crashes, the side effects hit, or nothing happens at all. Alex Kikel and I break down how to approach these compounds with an actual plan. We get into protocols for beat-up joints, lagging muscle groups, stubborn fat, cognitive performance, sleep, and pineal support. We also compare...

265. The Free Health Habits That Make Biohacking Work
The Kris Gethin Podcast
Biohacking has become the new status symbol. Everyone wants the chamber, the wearable, the peptide, the IV, the stem cells, the red light, and the expensive recovery tool. But there is a problem most people do not want to admit: the body may not respond to the expensive stuff if the foundation underneath it is weak. In this episode, I’m talking about the part of biohacking that does not look impressive online but changes how well everything else works. The part people skip before they spend thousands trying to fix their energy, sleep, recovery, hormones, body composition, inflammation,...

263. Can Tesamorelin Help You Burn Fat and Age Better?
The Kris Gethin Podcast
Discover the science behind Tesamorelin, a research peptide targeting visceral fat and promoting health span. Kris Gethin breaks down its mechanisms, research findings, and implications for fat distribution and longevity. Tesamorelin is a synthetic analog of growth hormone release hormone (GHRH), stimulating the pituitary to release endogenous growth hormone rather than supplying synthetic GH. It primarily targets deep visceral fat, especially around organs, instead of just superficial subcutaneous fat. Visceral fat is linked to metabolic diseases, inflammation, insulin resistance, and...

262. The Food Label Lie: Why Your “Healthy” Food May Not Be What You Think with Will Harris
The Kris Gethin Podcast
Most people think they know what they’re eating because they read the label. Grass-fed. Organic. High protein. Product of the USA. Low calorie. Clean ingredients. But that label is the end of the story, not the beginning. The beginning is the soil. The animal. The feed. The farm. The chemicals. The confinement. The way the food was raised, processed, mixed, marketed, and sold before it ever reached your plate. And that’s where a lot of people are getting fooled. In this episode of The Kris Gethin Podcast, I sit down with Will Harris, fourth-generation farmer and owner of White Oak...
info_outlineBryan Johnson's recent autoimmune diagnosis has sparked an important conversation throughout the biohacking community. In this episode, Kris Gethin explores what this moment means—not as a criticism of Bryan's dedication, but as an opportunity to ask bigger questions about health, longevity, and the limits of optimization.
Kris discusses the difference between collecting health data and creating true health, why modern lifestyles often disconnect us from our biological foundations, and how factors like sunlight, movement, grounding, nutrition, and resilience may matter more than endlessly stacking interventions.
This episode is a reminder that while technology can be an incredible tool, it should support our biology—not replace it. Ultimately, longevity may depend less on eliminating every risk and more on working with the way humans were designed to live.
