Frequently asked questions
What is Melanotan II?
Melanotan II (MT-2) is a synthetic cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone (α-MSH), with the sequence Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2. It is widely researched in wellness, melanocortin receptor, and pigmentation science.
What is the difference between Melanotan II and PT-141?
Both are synthetic peptides targeting melanocortin receptors and are structurally related — PT-141 (Bremelanotide) is a linear analogue derived from Melanotan II. Melanotan II is a cyclic heptapeptide acting non-selectively across multiple melanocortin receptor subtypes, while PT-141 has a more selective receptor profile. The two compounds have different molecular weights and CAS numbers.
What purity does Peptide Direct's Melanotan II meet?
All Melanotan II supplied by Peptide Direct is verified by HPLC analysis to a minimum purity of ≥98% on a batch-by-batch basis, with a Certificate of Analysis supplied on every order.
What strengths are available?
Melanotan II is available wholesale in 10mg, with flexible minimum order quantities for bulk buyers. Contact us if you require other strengths.
Can I get Melanotan II under my own brand?
Yes. Private label packaging, vials, and labelling are available for qualifying wholesale buyers. See our Private Label page for details.
How should Melanotan II be stored?
Store refrigerated at 2–8°C, away from direct light. For long-term storage, freezing conditions are recommended prior to reconstitution.
Is Melanotan II manufactured under GMP conditions?
Yes. All Melanotan II supplied by Peptide Direct is manufactured under GMP and ISO 9001:2015 certified conditions, the same standard applied across our full compound range.
