#387 – AMA #83: Peptides—Evaluating the Science, Safety, and Hype in a Rapidly Growing Field
Peter’s AMA on gray‑market peptides demystifies a fast‑growing, often misunderstood segment of the wellness industry. He introduces a four‑point framework—mechanism, evidence, safety, and regulatory status—to assess any peptide claim. The episode walks through real‑world case studies such as SS‑31, melanotan‑II, CJC‑1295 and BPC‑157, highlighting the stark contrast between FDA‑approved therapeutics and research‑only products. It concludes with a realistic view of what scientific validation and regulatory clarity are needed for peptides to become mainstream medicines.
