SupplementsDrug Developer Exposes the Science Gap Behind the Peptide Boom
Peptides are everywhere in wellness circles, marketed for everything from injury recovery to anti-aging. But how much of the hype is backed by real science? In this episode of The Proof, Simon Hill speaks with Dr. Leigh Baxt, a drug development expert, who explains the critical difference between FDA-approved peptide medicines and the largely unregulated compounds being sold online and injected by thousands of people. She walks through how drug development actually works, why most promising compounds fail before reaching humans, and why animal or cell studies are nowhere near sufficient to establish safety. She also challenges the common assumption that 'natural' means safe, and offers a framework for evaluating peptide marketing claims critically. This is a timely reality check for anyone navigating the peptide landscape.
