Product Overview
Melanotan I, also called afamelanotide, is a synthetic linear peptide analogue of the naturally occurring α-melanocyte-stimulating hormone (α-MSH). It is made up of 13 amino acids.
It shows high affinity for the melanocortin-1 receptor (MC1R), a receptor pathway mainly associated with pigmentation and photoprotection. Laboratory research has examined Melanotan I in melanogenesis and photoprotection studies, as well as in processes linked to oxidative stress and DNA damage repair.
