Addressing Loose Skin After Weight Loss: Realities and Solutions

What if the most powerful upgrades for brain energy, metabolism, and drive aren’t in mainstream medicine, but in rare peptides and misunderstood hormones? In this episode, you’ll discover the cutting-edge compounds, nootropics, and hormonal strategies that elite biohackers are using right now to optimize every part of their biology.

Host Dave Asprey sits down with Jay Campbell and Hunter Williams, co-founders of BioLongevity Labs—a performance biotech company creating oral peptide-based products like BioMind and BioGutPro. Jay is a globally recognized expert in testosterone optimization, author of The TOT Bible, and a leading voice in hormone and peptide therapeutics. Hunter is a high-performance coach and podcast host focused on metabolism, mindset, and men’s health through functional medicine and advanced supplementation. 

In this high-energy, high-clarity conversation, the trio explore what’s working right now in advanced human performance, spanning hormone synergy, mitochondrial enhancement, libido compounds, nootropics, and muscle-preserving stacks. You’ll hear why Dave injects estradiol three times per week, how Jay and Hunter use oral bioregulators to improve gut-brain signaling, and what peptides are quietly reshaping the future of health. 

 You’ll Learn: 

• Who should use estradiol—and how it can protect brain performance in men 

• The real role of testosterone and estradiol synergy in male health and longevity 

• How BioLongevity Labs is innovating with oral peptide delivery for cognitive and gut health 

• Why peptides like BPC‑157, TB‑500, PT‑141, and SS‑31 are changing mitochondrial care 

• The truth about Melanotan‑1, SLU, AOD‑9604, GW‑501516, and BAM‑15 

• What makes BioMind and BioGutPro different from standard nootropic or probiotic stacks 

• Why libido and metabolic health are deeply connected 

• The dangers of unvetted peptide sources—and what to look for in quality and bioavailability 

This is essential listening for anyone serious about biohacking, hormone optimization, mitochondrial support, brain energy, nootropics, neuroplasticity, functional medicine, sleep optimization, metabolism, and smarter-not-harder living.
