Melanotan I

How it works

The same tanning-hormone copy as afamelanotide, switching on MC1R in pigment cells, but sold online in vials as a tanning shot.

What it's made of

It is afamelanotide: 13 amino acids, alpha-MSH with two changes. Melanotan I was its lab name in Arizona; afamelanotide, its name as a drug. The product changes, not the molecule.

What it's for

Prescribed for

As a tanning agent, nothing. Only as the Scenesse implant, in erythropoietic protoporphyria.

Sold as

A tan without the sun that also protects you from burning.
