Melanotan II (MT-II) is a synthetic cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone (α-MSH). The structure includes an N-terminal acetyl group, a norleucine (Nle) substitution, and a lactam bridge between aspartic acid and lysine residues that supports peptide stability in laboratory matrices. MT-II is studied in published literature as a non-selective melanocortin receptor agonist at MC1R, MC3R, MC4R, and MC5R, and is supplied for in vitro receptor binding assays, cAMP accumulation models, and comparative signalling pathway research. Molecular identity aligns with PubChem CID 92432 (UNII UPF5CJ93X7). Supplied as 10 mg lyophilised powder with certificate of analysis. For research use only — not for human or animal consumption.

Every batch is verified at the manufacturer and re-tested when received in the UK. We send batches to a third-party lab where results cannot be manipulated — we do not rely on supplier testing or CoAs alone, so you get what you pay for. Each batch is independently analysed and supplied with a Certificate of Analysis (CoA) detailing purity, identity, and analytical method used. Batch-coded stock ensures full traceability from production to dispatch. Stock is held in laboratory-grade temperature-controlled storage and prepared using controlled thawing before dispatch. See our About page for full details. Additional documentation is available upon request for institutional procurement.
