Overview
Melanotan I (afamelanotide) is a melanocortin peptide. In an approved implant form (Scenesse), it treats a rare condition (erythropoietic protoporphyria); it is also sold on the gray market for tanning.
How It's Thought to Work
It stimulates melanocortin-1 receptors, increasing melanin (skin pigmentation) and offering photoprotection.
What the Research Says
The approved indication is supported by clinical trials; gray-market tanning use is a separate, unregulated context.
Regulatory & Legal Status
The approved implant (Scenesse) is prescription-only for a specific rare condition. Gray-market Melanotan I is unapproved.
Safety Considerations
Approved use is clinician-managed; unregulated injectable products carry added risk. Consult a qualified clinician.
