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.
Cross-checked against 50–100 independent sources per claim — the house standard. How this reference is checked
All are topical-only cosmetic peptides used in skincare formulations at low concentration (roughly 2-10%), with real if modest supporting cosmetic-science literature and negligible systemic absorption. The "needle-free botox" group — Argireline (SNAP-8), Vialox, Syn-Ake and Leuphasyl — all aim to relax expression lines by dampening nerve-to-muscle signalling; Matrixyl targets collagen and Eyeseryl under-eye puffiness. A meaningfully lower-stakes category than anything injectable in this book — topical use, by design, keeps these local to the skin.
