As we age, our bodies change — and so should our approach to training. In this episode, Kris Gethin shares his journey from competitive bodybuilding to a more functional, sustainable fitness routine as he navigates his 50s. He breaks down his current training split, why recovery now drives his results more than volume ever did, and how he stays mentally locked in even as the workouts themselves have changed.

• Why Kris moved away from six-day, heavy-lifting training as he entered his 50s
• How his goals shifted from pure muscle-building to functionality and long-term health
• The training split he follows now, and why fewer days doesn't mean less intensity
• What actually drives hypertrophy at this stage of life (hint: it's not more volume)
• How he approaches sleep, stress, and nutrition to support recovery
• Why seeking out discomfort is still central to his mindset, even with a lighter schedule

The peptide space is moving so fast that by the time a compound starts blowing up online, there is already something newer coming behind it. If you care about performance, recovery, body composition, hormones, or longevity, you need to know where this field is heading before the next wave of protocols and opinions hits your feed. Knowing what people are experimenting with now gives you a much better chance of separating something worth watching from another compound getting hyped to hell.

In this episode, Alex Kikel and I get into the new peptides, small molecules, and therapies starting to push this space forward. We talk about what is developing around mitochondria and endogenous hormone production, why Klotho is getting more attention, how far this conversation is moving beyond traditional peptides, and several compounds that could be names you hear a hell of a lot more about over the next few years.

Alex has spent roughly a decade studying and applying peptides, small molecules, bioregulators, and emerging compounds through his own experimentation and work with clients. His background also includes relationships with professionals connected to Eli Lilly and Pfizer, independent chemical synthesizers, consulting work on experimental compounds, and years of hands-on protocol development.

What's Discussed:

(00:00) Where the peptide industry is heading and the compounds starting to come down the pipeline.

(00:57) S-Mitochonic Acid 5-Ethyl Ester and why mitochondrial function is becoming such a major target.

(07:36) Phoenixin-20, neurological signaling, and endogenous hormone production.

(10:19) How Phoenixin-20 compares with enclomiphene, HCG, HMG, and kisspeptin.

(13:03) Klotho, recombinant Klotho, peptide forms, gene therapy, and why it is getting so much attention in longevity.

(21:46) Plasma exchange, EBOO, ozone, and young plasma.

(28:27) HDAP2, why Alex believes it could move beyond SS-31, and what happens when the dose is too much for the individual.

As usual, this episode is for education only. Some of what we discuss is still experimental, investigational, or needs proper medical supervision, so do your homework before you start playing with any of it.

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 injectable, transdermal, nasal, and oral delivery, because the same compound can perform very differently depending on how and where it is used.

Alex has spent roughly a decade studying and applying peptides, small molecules, and bioregulators through his own experimentation and work with clients. His education has also included direct relationships with professionals connected to Eli Lilly and Pfizer, independent chemical synthesizers, and years of hands-on protocol development, making him a credible voice for a topic that is often buried under hype, conflicting advice, and recycled information.

What's Discussed:

(04:05) Why advanced peptides still cannot replace training, nutrition, sleep, and recovery.

(08:35) Why peptide information has become harder to trust as more online experts enter the space.

(11:11) How BPC-157, TB-500, and Cartalax were discussed for joints, cartilage, and tissue repair.

(12:44) Using GHK-Cu and localized applications to support recovery and lagging muscle groups.

(17:23) The difference between IGF-1 LR3 for nutrient partitioning and IGF-1 DES for localized muscle signaling.

(20:16) BAM-15, yohimbine, SR-9011, and SLU-PP-332 for stubborn and localized body fat.

(28:01) Transdermal Noopept, intranasal NAD, Selank, and Semax for cognitive performance.

(36:16) Epitalon, delivery methods, pineal support, sleep, and the risks of excessive dosing.

(41:31) SANA/MBD-1, Tesamorelin, and growth hormone for fat mobilization and localized fat reduction.

Stay through the end for my TL;DR breakdown, where I condense the major compounds, their discussed applications, and the most important cautions into one final recap.

This conversation is for educational purposes only. Many compounds discussed are experimental, investigational, or require medical supervision.

What if optimizing your health isn't just about training, nutrition, supplements, and sleep—but about the trillions of microorganisms living within and around you?

In this episode, Kris sits down with Dr. Zach Bush to explore the microbiome and its potential influence on everything from digestion and brain function to hormones, athletic performance, recovery, and longevity.

Dr. Bush shares how his career evolved from conventional endocrinology into microbiome and environmental health research, and why he believes many of the health challenges we face today cannot be separated from the health of our soil, food systems, and environment.

They discuss the impact of modern agriculture, antibiotics, glyphosate, declining nutrient density, and environmental exposures on the microbiome, along with practical ways to support greater microbial diversity and resilience.

The conversation also explores the gut-brain axis, intermittent fasting, regenerative agriculture, and Dr. Bush's work developing Restore, including his theory that microbial communication may play a much larger role in human health and longevity than we currently understand.

• Why Dr. Zach Bush left conventional endocrinology to study the microbiome

• How soil health and modern agriculture may influence human health and nutrition

• What antibiotics, glyphosate, and environmental exposures can do to microbial diversity

• The gut-brain connection and its relationship with mood, cognition, hormones, and neurological health

• Why gut integrity and microbial diversity may matter for athletic performance and recovery

• How modern farming practices have changed the nutritional landscape of our food

• Intermittent fasting and the potential benefits of giving the gut time to repair

• Why different people can respond very differently to the same foods and diets

• The connection between our environment and microbiome resilience

• Regenerative agriculture and rebuilding healthier soil ecosystems

• The science and thinking behind Restore and microbial communication

• How supporting the microbiome could influence resilience, healthspan, and longevity

Bryan 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.

• What Bryan Johnson's autoimmune diagnosis means for the future of biohacking
• Why more health data doesn't always translate to better health
• The difference between optimizing biomarkers and optimizing human biology
• How modern indoor living affects health, resilience, and longevity
• Why sunlight, movement, grounding, and nature remain foundational
• Animal-based nutrition vs. plant-based diets for performance and healthy aging
• The importance of preserving muscle as we age
• EMF exposure: what we know, what we don't, and practical ways to reduce it
• Why resilience—not eliminating every challenge—is essential for long-term health
• The role of humility, curiosity, and evolving with new scientific evidence

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, focus, and health span. It is not that advanced tools have no place. It is that your body has to be in a position to use them.

I also share where advanced biohacking tools fit into my own routine, and why I think the order matters. If you have been chasing the newest longevity tool, tracking every metric, or wondering why you still do not feel the way you want to feel, this episode will make you rethink what actually makes biohacking work.

What's Discussed:

(00:04) Why the most expensive biohacks can still miss the real problem.

(02:26) What people are really trying to buy when they chase better energy, sleep, recovery, and health span.

(04:48) The lifestyle gaps no device, compound, clinic, or recovery tool can cover for you.

(06:31) The free layer of biohacking most people underestimate.

(08:08) Why the body needs the right foundation before advanced tools work well.

(15:30) The fat-loss and health-span mistake that can leave people lighter but weaker.

(23:42) How to use data, recovery tech, supplements, and advanced tools without turning them into expensive entertainment.
