Melanotan 1 Acetate

Melanotan 1 (often abbreviated as MT-1) is a synthetic peptide analogue of the body’s naturally occurring alpha-Melanocyte-Stimulating Hormone (α-MSH). Its primary and most studied function is to promote melanogenesis—the process where skin cells (melanocytes) produce melanin, the pigment responsible for skin color. While it shares a name with the more widely known Melanotan 2, MT-1 is a distinct peptide with a more selective mechanism of action, making it a key subject of research for applications related to skin pigmentation.
