PepEvolutionMelanotan I
Afamelanotide / Scenesse
FDA-approved 2019 (Scenesse) for a rare sun-sensitivity disorder — the clinically validated melanocortin agonist, but not for tanning.
Verdict — C · Emerging / Mixed
A real FDA approval for a narrow rare disease, with phase-3 evidence. The gray-market tanning use is unapproved and carries a milder but similar melanocytic concern to MT-II. The clinical pathway (EPP) is well-validated; the recreational pathway is not. Gray-market supply is extremely limited.
Overview
Melanotan I (afamelanotide, Scenesse) is a linear alpha-MSH analogue FDA-approved in 2019 for erythropoietic protoporphyria (EPP), a rare disorder causing severe pain upon sun exposure. Unlike Melanotan II it lacks the potent sexual/erectile activity but still stimulates eumelanin production. The approved indication has solid phase-3 RCT support; the gray-market tanning use case is a completely different and unapproved application. Sourcing outside an EPP prescription is essentially gray-market only.
