230: How to Fall Asleep (and Stay Asleep) Without Supplements
Most people pop melatonin or magnesium before fixing what truly matters, their sleep hygiene. In this episode, I break down how to fall asleep faster and stay asleep longer without supplements. We cover why deep sleep drives recovery, hormone balance, and emotional stability, and how missing just a few hours can accelerate aging and blunt performance. I share simple, science-backed ways to optimize your environment: blackout blinds, air filtration, room temperature, and sound control. You’ll also hear how tools like neurofeedback, red light, and grounding reset your nervous system and promote restorative rest. Plus, the habits that ruin sleep, late caffeine, blue light, and inconsistent bedtimes, and how to fix them. If you want better recovery, sharper focus, and more energy, start here. This is the blueprint for mastering sleep, no supplements required.

226. Why NAD3 Crushes NMN & NR (The Truth About Cellular Energy)
Most NAD+ supplements are fluff. NMN? NR? They’re precursors, half the story. In this episode, I break down why NAD3 isn’t just another molecule, it’s the master key for energy, recovery, and longevity. We get into the real science: how NAD+ fuels your mitochondria, repairs DNA, activates sirtuins, and slows aging at the cellular level. I explain why levels crash after 40, how stress, toxins, and training hammer your reserves, and why NMN/NR often fail thanks to CD38 and PARP overactivity. You’ll learn why NAD3 bypasses the weak links, how it stacks with spermidine, glutathione, and autophagy activators, and why Regen NAD is the one I actually use daily, because it works. Forget the hype. This is metabolic firepower that hits. If you’re overtrained, under-recovered, or want to stay biologically younger for longer: listen in.

225. Mike Ryan’s: Longevity at 59 and the Blueprint for Strength That Lasts
Most guys fall apart with age. Excuses pile up. Strength fades. But Mike Ryan proves you can get stronger every decade. At nearly 60, he’s outlifting men half his age, and he’s been doing it while training Hollywood’s biggest names like Dwayne “The Rock” Johnson . In this episode, we break down what actually drives longevity in fitness. Mindset over motivation. Why recovery, hydration, and sleep matter more than the latest trend. And why your environment will dictate your results more than any program. Mike gets real about TRT and peptides, the role of cheat days, and what decades at Gold’s Gym Venice have taught him about strength, discipline, and staying relevant. We also tackle overrated vs. underrated exercises, celebrity training under pressure, and how to avoid the social media nonsense that’s making lifters weaker. Mike Ryan is a Gold’s Gym Venice legend who’s trained top celebrities and athletes, including Dwayne “The Rock” Johnson. At nearly 60, he’s still pushing massive weight and proving that longevity comes from discipline, mindset, and consistency.

224. Why Oral Peptides Work (Even If “Experts” Say They Don’t)
“Destroyed by the gut.” “Zero absorption.” “Only injectables work.” This is BS. In this episode, I break down why oral peptides aren’t just working, they’re evolving. I cover the science, the delivery tech, and the results I’ve lived through: cartilage regrowth, hormonal optimization, cognitive firepower. You’ll learn how short-chain peptides bypass gut breakdown via PEPT1. Why nano-carriers, mucoadhesive polymers, and smart pH triggers are rewriting absorption. And why anyone still parroting the “oral doesn’t work” myth is stuck in 2005. I show you my travel peptide stack, how I keep everything cold, and why oral bioregulators like Sigma, Testolutin, and Biomind are now staples in my rotation. This isn’t hype. This is recovery, immunity, and performance…elevated. What's Discussed: (00:06) Oral Peptides: Why the “Destroyed by the Gut” Claim is BS (02:42) My Travel Stack: Fridge, Injectables, and Immune Armor (04:39) Brain on Fire: The Peptides That Keep You Sharp (08:19) Biohacking Absorption: How Oral Peptides Actually Work (16:54) What Makes Next-Level Recovery My Go-To for Gut Health: Glutamine and Imuno-IGG from Unmatched Supplements: https://www.unmatchedsupps.com/collections/digestion-gut-health Find more from Kris: Website: https://www.krisgethin.com/ Website:https://www.unmatchedsupps.com Instagram: @krisgethin Youtube: https://www.youtube.com/krisgethin 2 Shred: https://www.unmatchedsupps.com/products/2shred
You take creatine. You think it’s working. But if you’re bloated, cramping, or seeing zero gains, you’re not absorbing it right. Here’s the truth: monohydrate saturates one transport pathway. Once that’s full, you're done. Up to 30% of users feel nothing. Add GI issues and brain access problems, and you're building strength on a weak foundation. In this episode, I break down CreGAAtine, a next-gen formula with creatine monohydrate, GAA, and B vitamins. It hits four pathways, not one. That means better muscle saturation, stronger brain uptake, and zero bloating. I cover absorption, ATP regeneration, neuroprotection, and why this crushes the “non-responder” excuse. You get more power, more cognitive resilience, and faster recovery, without these side effects. I show you how I take it, why it works year-round, and how it fits into a performance-first lifestyle. Listen in. Then upgrade your creatine. Your strength, brain, and gut will thank you. What's Discussed: (00:01) Evolution of Creatine (01:22) Limitations of Monohydrate (04:13) Brain Absorption & Non-Responders (05:26) What Makes CreGAAtine Different (11:42) Benefits of Creatine Supplementation Thank you to our sponsors: NAD + Cell Shield from Biostack Labs https://biostacklabs.com/kris BiOptimizers - code KRIS10 for 10% off https://bioptimizers.com/ My Go-To Creatine: CreGAAtine from Unmatched Supplements: https://www.unmatchedsupps.com/cregaatine-capsules Find more from Kris: Website: https://www.krisgethin.com/ Instagram: https://www.instagram.com/krisgethin/ Youtube: https://www.youtube.com/krisgethin 2 Shred: https://www.unmatchedsupps.com/products/2shred
