What Is Melanotan II?
Melanotan II (MT-II) is a synthetic cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone (alpha-MSH). Unlike the linear 13-amino acid natural peptide, MT-II's cyclic structure confers resistance to enzymatic degradation and a longer plasma half-life. It acts as a non-selective melanocortin receptor agonist, binding MC1R, MC3R, MC4R, and MC5R.
Preclinical research has studied MT-II across melanogenesis and photoprotection (via MC1R), appetite and energy homeostasis (MC3R, MC4R), and sexual function models (MC4R). It is also the parent compound of PT-141 (Bremelanotide), a more receptor-selective metabolite available separately from Eternal Peptides Wholesale as PT10.
For selective MC3R/MC4R research, see the PT-141 page. For research use only.

Frequently Asked Questions
Where can I buy Melanotan II in Australia? +
Eternal Peptides Wholesale is an Australian-owned, online distributor supplying Melanotan II for research purposes. MT10 (10mg, box of 10) is $396.00. Kovera Labs reports with COA on product page. see Shipping Policy for dispatch estimates. For research use only.
What is Melanotan II used for in research? +
MT-II is used in melanogenesis and photoprotection research (MC1R), appetite and energy balance models (MC3R, MC4R), and sexual function studies (MC4R). Its non-selective receptor profile makes it a broad tool for melanocortin system research. For research use only.
How does Melanotan II differ from PT-141? +
MT-II activates MC1R, MC3R, MC4R, and MC5R. PT-141 (Bremelanotide) is a metabolite of MT-II with more selective activity at MC3R and MC4R, with reduced MC1R activity. Research using PT-141 can therefore isolate MC3R/MC4R effects with less confounding MC1R-driven melanogenesis. See the PT-141 page. For research use only.
