Melanotan I (afamelanotide) is a linear synthetic analogue of the endogenous peptide alpha-melanocyte stimulating hormone (α-MSH). Research has examined its binding affinity at melanocortin receptors, particularly MC1R, and its role in melanogenesis signaling pathways.

Preclinical and clinical studies have investigated its potential in photoprotection research and pigmentation biology. Its non-cyclic structure distinguishes it from Melanotan II in receptor selectivity research.

Each vial is supplied as lyophilized powder, third-party tested via LC-MS analysis, and ships with a Certificate of Analysis.
