Afamelanotide

Synthetic alpha-MSH (MC1R) analog

A synthetic analog of alpha-MSH, approved as Scenesse (a subcutaneous implant) for the rare light-sensitivity disorder erythropoietic protoporphyria. It is the same molecule as melanotan I.

Mechanism under study

Afamelanotide is a melanocortin-1 receptor (MC1R) agonist that stimulates production of the dark pigment eumelanin, increasing photoprotection of the skin.

Research-reported dosing

FDA- and EMA-approved (as Scenesse) for erythropoietic protoporphyria — a 16 mg subcutaneous implant roughly every two months. Research use of the free peptide (melanotan I) is not clinically established.

Reconstitution

Based on a standard 10 mg vial: with 2 mL bacteriostatic water = 5,000 mcg/mL (5 mg/mL); 1 unit ≈ 50 mcg.
