Have you heard that RFK just pushed a plan to fast-track 12 specific peptides toward regulatory approval — and you have no idea which ones are actually worth your attention? You're not alone. The peptide space is a minefield of hype, gray-market sourcing, and very thin human evidence, and sorting signal from noise takes hours of digging through research most people don't have time to read.
Here's the frustrating reality: most peptide content online either oversells everything as a miracle compound or dismisses all of it as unproven nonsense. Neither extreme helps you make a real decision. You end up either spending money on something with almost no human data behind it, or you miss out on a compound that genuinely could move the needle for your recovery, sleep, cognition, or body composition.
Imagine having a clear, honest breakdown of all 12 peptides on RFK's list — ranked by evidence strength, benefit potential, and real trade-offs — so you can walk into any conversation with a doctor or coach knowing exactly what you're talking about. You'd know which two peptides have solid human pharmacology data and are very likely to work. You'd know which five have plausible benefits but need more research before committing. And you'd know which ones are so early-stage that even a gray-market enthusiast would pump the brakes.
Dr. Mike Israetel of Renaissance Periodization is one of the most credentialed and candid voices in evidence-based fitness. He holds a PhD in Sport Physiology, has co-founded one of the most respected coaching organizations in the industry, and — by his own cheerful admission — has personal experience navigating gray-market compounds. When he says a peptide needs more human trials before he'd touch it, that means something. When he says one is a heavy hitter, you can take that seriously.
This checklist distills Dr. Mike's full breakdown of every single one of the 12 peptides into a clean, scannable action guide. Each step gives you the compound name, its primary claimed benefits, its evidence tier, its known downsides, and a clear verdict on where it sits in the ranking. You'll also get guidance on what to watch for as these peptides move through the regulatory process and how to think about each one if and when a doctor can prescribe them legally.
Stop guessing. Use this checklist to evaluate all 12 peptides intelligently, understand the real evidence behind each one, and make confident decisions about your health.
Every checklist item comes with actionable notes to guide you — things like "Don't forget to do this before you start," "Avoid this common mistake," or "Set a reminder for 30 days out." Nothing vague, just clear next steps.
