How to read this library

We include landmark Phase 3 RCTs, key mechanistic papers, safety reports, and — when a peptide is mostly anecdotal — a sober summary of what human data actually exists. A citation's presence here does not imply endorsement of its conclusions; context on each peptide's page explains how weight should be assigned.
