All episodes
GLP-1s, Peptides & the Future of Regulation
The GLP-1 gold rush, gray-market peptides, and the regulatory storm brewing behind it all — a no-holds-barred conversation.
Why Everyone Will Be on Peptides Soon
Twelve minutes on why peptides are about to become the new supplement stack — and what to try first.
PepTalk Trailer
What PepTalk is really about, in 74 seconds. Peptides, longevity, and the frontier of human performance.
Where to go deeper on peptides.
A curated shortlist of the research, communities, and clinicians we actually trust — the stuff we point people to after every episode.
- ↗NIH / National Library of Medicine
PubMed
Peer-reviewed research on peptides, GLP-1 agonists, BPC-157, and longevity therapeutics — the primary source we cite on the show.
- ↗U.S. National Institutes of Health
ClinicalTrials.gov
Every active and completed peptide clinical trial in the world. Search by compound to see what's actually being tested in humans.
- ↗IPS
International Peptide Society
Professional body for physicians and researchers working with therapeutic peptides. Practitioner directories and continuing education.
- ↗American Academy of Anti-Aging Medicine
A4M — Peptide Therapy Certification
Where most credentialed peptide practitioners in the U.S. get trained. Useful if you're looking for a qualified doctor.
- ↗U.S. Food and Drug Administration
FDA — GLP-1 & Compounded Drugs
Official FDA guidance on semaglutide, tirzepatide, compounding, and the gray-market landscape we cover every week.
- ↗Independent research aggregator
Examine.com
Unbiased summaries of the evidence behind supplements and peptides. Great sanity check before you try something new.
- ↗Reddit community
r/Peptides
The largest public peptide community. Anecdotal but useful for real-world dosing, sourcing, and side-effect patterns.
- ↗Longevity & performance medicine
Peter Attia — Drive Podcast
Deep, technical episodes on GLP-1s, metabolic health, and longevity from a physician we frequently reference on PepTalk.
Follow @PepTalk for the clips.
60-second peptide breakdowns, guest highlights, and the stuff that didn't make the final cut. New drops daily.
Gregory Gopman is a founder and operator exploring the frontier of human biology.
Through PepTalk, Gregory hosts unhurried conversations with the scientists, physicians, and builders working on peptides, GLP-1s, longevity therapeutics, and the systems that will bring them to everyone. The show sits at the intersection of research, clinical practice, and the regulatory reality shaping what's possible.
Each episode goes deep enough to be useful — for patients weighing options, for founders building the next wave of health companies, and for anyone who wants to understand where the human performance frontier actually is, not where the headlines say it is.
