What this video covers
We got our favorite fellow Docs Who Lift here back for maybe the third time or so. Austin Baracki, who recently joined my team at Vineyard, and we have Dr. Jordan Veenbomb, who both are part of the barbell medicine crew. Today we’re going to be talking about peptides, what the hell they are and what they do and what is the data behind them.
Summary drawn from this video’s own transcript (banked in our research library, pulled 2026-11-07). Claims below are the speaker’s — attributed, not endorsed. This site publishes no dosing, protocol, or sourcing information.
Key points, in the speaker’s own framing
- So to to summarize, peptides, umbrella term, short chain amino acids put together that then have in what people term as peptides because peptides could be anything even stuff that we ingest that have other functions.
- So you want some sort of flexibility around like look, we have some evidence of like safety and efficacy, but you don’t need like ironclad stuff just to get it approved.
- As far as stuff we have evidence on, a surprising number of them we do have like phase one, phase two clinical trial stuff on, but most of them just don’t work, which is why they were abandoned.
- When people are like, “FA approval doesn’t matter to me.” I’m like, “So, you would take a medication to lower your blood pressure that’s not FDA approved over one that is FDA approved?
- But suggesting that something that is not FDA approved is somehow safer than things that are FDA approved that uh yeah that kind of gets me a little hot under the collar.
- We have the animal studies before ever moving on to these small, you know, 20 to 80 healthy people phase one trials just to test the the pharmacocinetics and the pharmacodnamics initial safety signals.
