In this episode with Dr. Matt Cook, recorded days after he returned from Washington, D.C., you'll receive a breakdown of what just happened to peptides in the US. You'll hear what the FDA's Pharmacy Compounding Advisory Committee actually voted on, why seven popular peptides were pulled two years ago, which six of the seven were just recommended for the bulk list, which one was left off, and what all of it means for your ability to get peptides legally from a pharmacy instead of the gray market. Dr. Cook also explains why peptides behave so differently from ordinary drugs, walks through a safety review covering millions of doses, and shows how our new company, LIFE OS, pulls your labs, wearables, and genetics into one HIPAA-compliant place. And if you want to keep every peptide straight, you’ll gain access to his peptide cheat sheet that covers what each one does, how to dose it, and where to source it.

Save 20% on the Only Clinically Proven Urolithin A Supplement 🧬⚡
One of the biggest reasons energy declines with age isn't that your body stops producing energy...

It's that your cells become less efficient at renewing the mitochondria responsible for producing it. As damaged mitochondria accumulate, strength, endurance, recovery, and cellular energy all begin to decline.
That's why I recommend checking out Timeline Nutrition's Mitopure®, the only clinically validated Urolithin A supplement, delivering a precise dose of a naturally occurring compound that supports mitophagy, your body's process of clearing out worn-out mitochondria so healthier ones can replace them.
What impresses me most is the science. Mitopure® is backed by more than 18 years of research, over 25 human clinical trials, and studies showing it can increase mitochondrial renewal by 39% after 16 weeks. Clinical research has also demonstrated benefits for muscle strength and cellular energy, making it one of the few longevity supplements with this level of human evidence.
If your goal is to stay stronger, recover faster, and maintain high levels of energy as you age (not just rely on another stimulant), Mitopure® is one of the most compelling options available.
You can try Mitopure® for yourself and save 20% off with code BEN here.
