Dr. Leigh Baxt, a drug development expert, deconstructs the peptide boom sweeping wellness culture. She explains what peptides actually are, how the FDA drug development process works, why most compounds fail to become medicine, and why the claims circulating online far outpace the evidence. The episode separates approved peptide drugs from unregulated online products and explores the critical gap between promising lab results and proven human safety.

FDA-Approved vs. Unregulated Peptides: A Critical Distinction08:03
Peptides sold online are almost universally unregulated research compounds, not medicines. FDA-approved peptides have undergone years of human testing; online peptides have not.
The majority of compounds that show promise in labs never become approved medicines. The drug development process is a funnel where most ideas fail before reaching humans.

Personal success stories with peptides sound convincing but cannot establish causation, safety, or efficacy—they're the starting point for clinical research, not the endpoint.
