Most supplement brands are all hype, under-dosed, overpriced, and packed with fillers. Biostack Labs is different. In today’s episode, I’m sitting down with Adam Gethin to talk about the science behind real health optimization, the future of supplementation, and why most people are wasting their money on garbage formulas that don’t deliver results.

We’re breaking down how NAD+ impacts aging, why blood sugar regulation is the key to metabolic health, and the top supplements every serious athlete should be using.

I’ll also cover why NAD IVs are a waste of time (and money), the best way to boost glutathione for immune defense, how inflammation wrecks your gains (and how to fight it), and why metabolic health should be your #1 priority for longevity.

Adam Gethin is the founder of Biostack Labs, a brand redefining the supplement industry with research-backed formulas designed for longevity, recovery, and peak performance. With a background in coaching, content creation, and digital marketing, Adam has worked with some of the biggest names in fitness, helping brands and athletes optimize their approach to health and performance.

Today’s episode is a Q&A, and I’m tackling your biggest questions on training, nutrition, and longevity, no fluff, just real, actionable answers. If you’re feeling stuck, overwhelmed by conflicting advice, or just want to make sure you’re doing everything right, this episode is for you.

A lot of guys are training hard but still not seeing the results you should. Maybe your testosterone is tanked, your recovery is trash, or you’re wasting time cycling supplements you don’t even need. I’m breaking down what actually works, how to optimize your hormones, whether creatine cycling is legit or BS, which peptides are worth your money, and how to stay dialed in with your diet no matter what life throws at you.

I’ll also cover why most guys are sabotaging their testosterone levels without realizing it, the biggest mistakes in creatine supplementation, how to cut through the noise and build a nutrition plan that actually works for you, and why peptides aren’t the magic muscle builders people think they are (but can still be a powerful tool if used correctly.)

If you’re ready to stop second-guessing your approach and start applying strategies that actually deliver results, hit play now!

Lifting heavy and eating big isn’t enough, if you’re not optimizing recovery, hormones, and performance, you’re making this way harder than it needs to be. Most people train their asses off but completely ignore the science-backed biohacks that can take muscle growth to the next level. You can keep guessing, or you can start working smarter.

In this episode, I’m giving you 5 next-level muscle-building biohacks that I’ve personally tested and refined over years of training, coaching, and biohacking my own body. Tracking blood glucose to maximize carb uptake, sleep and HRV monitoring to dial in recovery, red light therapy for testosterone optimization, it’s all here. These aren’t gimmicks, they’re real strategies that give you the edge.

I’ll also break down why your training intensity is useless if your recovery is trash, how cold exposure can skyrocket testosterone, and why ignoring blood and DNA testing is keeping you from unlocking your full potential.

You want to build serious muscle? Then stop guessing and start applying what actually works. Tap in, take notes, and let’s get to work.

You can train hard, stay disciplined, and push your limits, but if your environment, stress levels, and daily routine aren’t dialed in, you’re setting yourself up for failure. Most people focus on workouts and nutrition but completely ignore the biggest factor in long-term success: their surroundings.

In this episode, Sibylle and I are recording from Tulum, where we’ve been setting up our second home…and let’s just say, it hasn’t been smooth sailing. We’re talking about the challenges of inefficiency, the stress of unpredictability, and how distractions can wreck your ability to stay consistent. I’ll break down why your environment dictates your results, how to build resilience when things don’t go as planned, and why efficiency is the ultimate performance hack.

We’re also sharing details on our April retreat, where we’re bringing together top experts in fitness, biohacking, and longevity for an immersive experience designed to level up your health and performance. Plus, we’ll clear up the confusion about my departure from Kaged Muscle and why we’re building something even bigger.

If you’re serious about upgrading your mindset, training, and results, this episode is a must-listen.

Today's guest is a leader amoung the biohacking circle, the one and only Ben Greenfield. Ben is a health consultant, speaker, and New York Times bestselling author of a wide variety of books including the widely popular titles Beyond Training, Boundless, Fit Soul, Spiritual Disciplines Journal, the Boundless Cookbook and Endure. A former collegiate tennis, water polo and volleyball player, bodybuilder, 13-time Ironman triathlete and professional obstacle course racer, Ben has been voted by the NSCA as America’s top Personal Trainer and by Greatist as one of the top 100 Most Influential People In Health And Fitness. 

A frequent contributor to health and wellness publications and websites and a highly sought-after speaker, Ben’s understanding of functional exercise, nutrition, and the delicate balance between performance and health has helped thousands of people around the world achieve their goals and improve their quality of life–from high-level CEOs to soccer moms to professional athletes and beyond. Ben also seeks to teach and inspire people to fully experience and joyfully savor all of God’s creation while optimizing their physical health

Before arriving in Delhi, Ben and Kris discussed the workout plans and challenged themselves to stick to it, ensuring accountability for their fitness goals. During the intense workout session, they incorporated a concurrent style of training, combining strength exercises with cardio intervals to maximize efficiency and effectiveness. The structured routine included kettlebell exercises like alternating overhead presses and swings, followed by four-minute cardio bursts on the bike, providing a comprehensive full-body workout. Additionally, they integrated recovery exercises such as planks, emphasizing the importance of active recovery to optimize mobility and overall performance. This holistic approach to training not only enhances physical fitness but also cultivates mental resilience and discipline, driving consistent progress towards their fitness aspirations.

Fatigue, and sluggishness, exploring conditions such as mold sensitivity, Epstein-Barr virus, and Lyme disease were a few of the topics discussed in this episode. By examining physiological parameters like thyroid function and conducting lab tests for mycotoxins and hormone levels, individuals can gain insights into potential health challenges. The conversation highlights the vital concept of the body as a battery, operating with an electrochemical gradient that can be influenced by environmental factors. Living in a modern world characterized by an "ancestral mismatch," where sedentary lifestyles and exposure to electronic devices prevail, drains the body's energy reserves. Key strategies for recharging include exposure to sunlight for ATP production, grounding to absorb negative ions from the Earth, and replenishing electrolytes with mineral-rich salts. Embracing biohacking tools like infrared lighting and optimizing sleep environments by minimizing exposure to electromagnetic fields during the night are crucial steps towards mitigating energy depletion and enhancing overall well-being.

Key Takeaways

• Accountability through pre-planned workouts facilitated adherence to fitness goals, fostering commitment and consistency in training efforts.
• Integration of concurrent training methods, combining strength exercises with cardio intervals, maximized workout efficiency and provided a comprehensive approach to physical conditioning.
• Understanding the body as a battery underscores the importance of actively recharging it amidst modern lifestyle challenges.
• Implementing simple yet effective strategies such as sunlight exposure, grounding, and mineral supplementation can help counteract the draining effects of environmental stressors on the body's energy reserves.
