Melanotan 2 (MT-2) is a synthetic cyclic heptapeptide analog of a-melanocyte stimulating hormone (a-MSH) that stimulates melanin production in the skin. It also has a range of peripheral effects. For instance, it is thought to increase libido, reduce fat catabolism in muscle-type tissues, and decrease cholesterol metabolism.
