Melanotan 1 10mg x10

Melanotan 1 is a synthetic peptide similar to the endogenous alpha-melanocyte stimulating hormone (α-MSH).⁽¹⁾ Melanotan 1 comprises 13 amino acids, the same as α-MSH, but differs by only two amino acids from the endogenous peptide hormone. This structural difference is why researchers suggest the synthetic peptide may exert a higher affinity towards the target cells and boast a longer half-life. According to research, the two notable modifications include the substitution of methionine and L-phenylalanine at the fourth and seventh positions with norleucine and D-phenylalanine, respectively.
