Melanotan 2

Melanotan II (MT-II) is a synthetic cyclic heptapeptide strictly designated for in-vitro and pre-clinical laboratory research. It is structurally engineered as a lactam-bridged analog of the endogenous peptide hormone alpha-melanocyte-stimulating hormone (α-MSH). To enhance its functional potency, MT-II features a specific cyclic molecular structure with the exact sequence Ac-Nle-Asp-His-D-Phe-Arg-Trp-Lys-NH2 (cyclic 2-7). This highly specialized conformation grants it super-potent melanotropic activity during in-vitro assays. In laboratory studies, Melanotan II is widely investigated for its primary role in stimulating melanogenesis. By interacting with melanocortin receptors, the peptide triggers melanocytes to increase the production and secretion of melanin. Beyond its melanotropic effects, MT-II is utilized in research models to explore its mild fat-mobilizing properties and its pronounced influence on arousal mechanisms.
