About Melanotan I

Melanotan I (afamelanotide) is a synthetic analogue of alpha-melanocyte-stimulating hormone that stimulates melanin production for a protective, sun-independent tan. Compared with Melanotan II it is more selective, producing pigmentation with fewer off-target effects such as libido changes. It is researched for photoprotection and even skin pigmentation.
