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. In the United States, most of these compounds are not FDA-approved and are sold for laboratory research only; a few are prescription drugs, and some are controlled substances or banned in sport. Possessing or administering an unapproved compound outside an authorized setting may be unlawful. Nothing here is a recommendation to buy, possess, or self-administer anything. Consult a licensed physician before any decision involving peptide use.
Not reconstituted — topicaldelivery, so there's no vial to draw from.
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.
