The Book of Peptides is not a clinic and not your doctor. We do not sell, prescribe, recommend, or personalize any compound, and no grade or ranking here is an endorsement. None of the compounds covered are approved for the uses described here by the U.S. FDA, Australia's Therapeutic Goods Administration (TGA), New Zealand's Medsafe, or the equivalent regulator in most other countries.
Most are sold for laboratory research only, a few are prescription-only drugs, and some are controlled substances or banned in sport. Possessing or administering an unapproved compound outside an authorized setting may be unlawful wherever you live. Nothing here is a recommendation to buy, possess, or self-administer anything. Consult a licensed physician before any decision involving peptide use.

Eli Lilly's selective amylin receptor agonist — a once-weekly satiety-hormone mimic on a different axis than the GLP-1 class, without cagrilintide's dual amylin/calcitonin activity. Its 48-week Phase 2 trial (NCT06230523, 263 adults, published in The Lancet, November 2025) reported 9.5–20.1% mean weight loss across dose arms versus 0.4% on placebo; five Phase 3 trials have been enrolling since December 2025.
