MT-2 (Melanotan 2 Acetate)

Melanotan 2 (MT-2) acetate is a synthetic peptide hormone, specifically an analog of alpha-melanocyte-stimulating hormone (α-MSH), designed to induce skin tanning without UV exposure. It acts as a melanocortin receptor agonist (MC1R, MC3R, MC4R, MC5R), and is used for tanning, increased libido, and appetite suppression, often with severe side effects like nausea and vomiting.
