Melanotan II
Melanotan II (MT-II) is a synthetic cyclic analogue of α-melanocyte-stimulating hormone, described in the literature as a non-selective melanocortin agonist across MC1R, MC3R, MC4R and MC5R. Supplied as a pre-loaded multi-dose injector pen for research and laboratory use only.
Sequence: Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2. Its non-selectivity is the principal published distinction from PT-141, which shares the same cyclic scaffold but is characterised as acting mainly at MC4R/MC3R — receptor selectivity being a key variable when interpreting melanocortin research.
Every batch is HPLC-verified by an independent laboratory. Certificates of Analysis are published on the product page as each batch is verified — ask us if you need the report for a specific batch. Store at 2–8 °C in the dark.
