Topic summary
Understand why two approved medicines can have narrow, different uses without proving broad tanning or performance claims.
What these peptides have in common
Three peptides act on melanocortin receptors and end up in very different places. Bremelanotide (PT-141) has an FDA-approved product for one narrow indication. Afamelanotide (Scenesse) has an FDA-approved implant for a rare-disease indication. Melanotan II is graded Insufficient, and its brief records no approved product in any jurisdiction reviewed.
The receptor family is shared; the evidence is not. Two approvals for two specific conditions do not license a general tanning, libido, or performance claim for a third molecule, a different route, or an unapproved product. Each brief states the exact condition and endpoint that was studied.

- Approved human outcomesApproved products have evidence from studies in people that measured health results for specific uses. This does not show that every product, person, or use has the same result.EstablishedAn official agency review or strong, repeated studies in people support one clear use. That evidence applies only to the product, people, and use we reviewed. It does not mean the product is safe or effective for everyone.
Bremelanotide
An approved medicine for one defined sexual-desire disorder. It is not a general sexual-performance enhancer.

Afamelanotide
An approved implant that increases pain-free light exposure in adults with EPP. It is not a general tanning or cosmetic peptide.

This did not establish a health benefit on its own.InsufficientReliable studies in people are missing, too limited, or do not support the claim. This does not prove that the substance has no effect on the body.
Melanotan II
An unapproved tanning peptide. Two small older studies measured pigment and erectile effects, while serious harms appear in case reports and the supply chain is unverified.
