MT-2
10mg · £39.99
Melanotan 2 — also written MT-2 — is a cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone, acting as a non-selective melanocortin receptor agonist. Sequence Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2.
The published literature includes case reports of adverse events. Peters and colleagues reported a case of renal infarction associated with Melanotan II in CEN Case Reports in 2020, alongside a review of earlier reports. Anyone handling this compound should be aware that literature exists.
Mechanism in the literature
Melanotan 2 is a non-selective agonist across melanocortin receptor subtypes, which is the pharmacological distinction from more selective analogues in the same family. Work on cyclic heptapeptides carrying the His-Phe-Arg-Trp message sequence of alpha-melanotropin describes the structural basis of that activity.
This compound is unapproved in every major jurisdiction, and the case-report literature documents serious adverse events in people who have used unregulated material. It is supplied strictly for laboratory research and is not for human or animal consumption.
Handling and reconstitution
Supplied lyophilised at 10mg. Room temperature before reconstitution, diluent down the vial wall, gentle swirling.
Storage and stability
Lyophilised at -20°C, protected from light. Reconstituted solution refrigerated and used within a short window.
Common questions
Is a certificate of analysis available for Melanotan 2?
Not for the current batch. No purity figure appears on this page because we do not hold analysis for it yet; certificates are issued with orders for the compounds where we do.
Why is it listed as both Melanotan 2 and MT-2?
They are the same compound. MT-2 is the abbreviation printed on the vial label; Melanotan 2 is the name it is more commonly known and searched by, so that is what the page is titled.
