Melanocortin Peptides is a recurring topic in our peptide coverage. This hub collects every article tagged Melanocortin Peptides, newest first, each evidence-graded and tied to real, verifiable sources.
An evidence-graded look at the melanocortin 'tanning peptides' — separating the one FDA-approved rare-disease drug (afamelanotide) from the unregulated, illegal-to-sell melanotan-2 'tan jabs' linked to melanoma, priapism and rhabdomyolysis.
An evidence-graded look at the melanocortin peptides marketed for a tan or 'natural photoprotection' — separating the one FDA-approved rare-disease drug (afamelanotide) from the unregulated, illegal-to-sell melanotan products linked to melanoma and priapism.
A clinical-editorial ranking of the peptides studied for male low libido — PT-141, kisspeptin and gonadorelin — graded honestly. The strongest evidence for male desire is correcting low testosterone, not a peptide.
A clinical-editorial ranking of the peptides studied for erectile dysfunction — melanocortin agents (PT-141, melanotan-2) and kisspeptin — graded honestly against the AUA first-line standard. No peptide is FDA-approved for ED.
A clinical monograph on Melanotan II (MT-II) — the non-selective melanocortin agonist sold illegally for tanning. Thin 1990s human data, a high-risk safety profile, and an unapproved 2026 legal status.
A clinical monograph on Melanotan I — INN afamelanotide, marketed as SCENESSE — the only FDA-approved melanocortin agonist, with Grade-A EPP photoprotection data and a separate unapproved gray-market tanning identity.

Yes. Every article here grades its efficacy claims A-D and cites real, verifiable studies, regulatory documents or trial registries.
The majority of compounds documented here are not approved by the FDA for human use. Approved drugs (e.g. semaglutide, tirzepatide) are noted explicitly and require a licensed prescriber.
Many peptides — including BPC-157 and GHK-Cu in injectable form — are sold strictly "for research use only — not for human consumption." Purity, identity, and dosing of such products are not regulated or guaranteed.
Several compounds are banned in competitive sport under the WADA Prohibited List. Athletes risk sanction regardless of intent or formulation.
