Peptides sit at the intersection of biological plausibility, clinical promise, and aggressive commercialization, and are often marketed as cutting-edge therapies for everything from muscle repair and longevity to cosmetic enhancement. Rather than promoting or dismissing peptides wholesale, Peter lays out a clear, repeatable framework for evaluating any peptide or drug—covering mechanism, intended effects, safety, dosing, and alternatives. He distinguishes FDA-approved peptide therapeutics from the loosely regulated "peptides" common in biohacking culture; examines the strengths and limitations of animal and human evidence; unpacks manufacturing, gray-market sales, "research use only" labeling, and third-party testing; addresses oral peptides and absorption challenges; and explains how patents and incentives shape which compounds advance through clinical pipelines. The discussion concludes with a sober look at what would need to change for peptides to become broadly usable therapies, where legitimate peptide therapeutics may expand next, and which areas of medicine stand to benefit most right now.
