Melanotan II is a synthetic analogue of the melanocortin peptide hormone alpha-melanocyte stimulating

hormone (α-MSH) that occurs naturally. In usage, Melanotan II has been revealed to have aphrodisiac and

melanogenesis (tanning) effects that have been subjected to clinical trials and preliminary studies. The

compound is a cyclic lactam analogue of α-MSH that has an amino sequence named MTII (Ac-Nle-c[Asp-

His-D-Phe-Arg-Trp-Lys]-NH2). Notably, no government drug regulatory agency across the world had approved

for the use of any compound incorporating the Melanotan II peptide by 2010.


Malanotan II is used for tanning of the skin and producing of erections in men with erectile dysfunction when

administered as a shot under the skin. Malanotan II is safe when used under strict medical supervision for

treating erectile dysfunction. However, it may cause stomach cramps, tiredness, nausea, spontaneous

erections of the penis, and darkened skin.


Melanotan II is widely sold online and in beauty salons as well as gyms as melanotan in their marketing.

These products purport to contain the same chemical composition as afamelanotide. These products have

been declared illegal and do not have the same chemical components as Melanotan II. As such, countries

issues warnings against their use.
