18 peptides, each with a one-line verdict and the evidence behind it. The badge shows the strongest tier any claim in the entry reaches, so an “Established” badge means at least one claim rests on an approval or a pivotal trial, not that everything does. How the tiers work.

Melanocortin receptor agonist
The FDA-approved libido peptide that skips the vascular route.
A cyclic melanocortin-receptor agonist that acts centrally on sexual desire rather than on blood flow. It is FDA-approved (Vyleesi, 2019) for acquired hypoactive sexual desire disorder in premenopausal women, based on two Phase 3 trials. Structurally it is the near-twin of melanotan II — differing by a C-terminal acid.

- Melanotan IIClinical
Melanocortin receptor agonist
The tanning-and-libido peptide that never made it to approval.
A broad-spectrum melanocortin agonist studied for pigmentation and sexual function. Its mechanism is well characterized, but it has no regulatory approval and carries documented safety concerns from unregulated use — a frontier compound with real caveats.
