Melanotan 2

Melanotan II (MT-2) is a synthetic analog of the naturally occurring peptide alpha-melanocyte-stimulating hormone (?-MSH). It binds to melanocortin receptors, especially MC1R, to stimulate melanin production in the skin — resulting in a deeper, longer-lasting tan without the need for excessive sun exposure. Originally developed as a skin cancer prevention tool, MT-2 has gained popularity for its cosmetic tanning effects, and its unexpected benefits for libido and erectile function have further broadened its appeal.
