| Mechanism (summary) | Melanotan II is a synthetic cyclic analogue of α-melanocyte-stimulating hormone. It has never obtained mainstream regulatory approval and appears in official warnings as an unlicensed or unapproved product. Dosing, purity, sterility, and composition of gray-market products are usually not standardized. |
| Dosing notes | Human trial dosing was subcutaneous, often beginning with 0.005 mg/kg increments toward 0.025–0.03 mg/kg. There is no authoritative approved dosing schedule and no standardized contraindication list because the drug is not licensed. |
| Storage |

Unspecified in authoritative regulated labeling — no approved patient product exists. Research-grade peptide handling: lyophilized storage at -20°C or colder, protected from light and moisture; aliquot after reconstitution to avoid repeated freeze-thaw. |
