What Is Melanotan II? A Research Overview
A plain-language research overview of Melanotan II (MT2) — what the melanocortin agonist is, why it's studied, and how purity is verified. Research use only.
Melanotan II — often written MT2 — is a widely searched research peptide in dermal and melanocortin science. This overview explains what it is, why it draws laboratory interest, and what to check when sourcing it.
What Melanotan II Is
Melanotan II is a synthetic cyclic analogue of alpha-melanocyte-stimulating hormone (α-MSH), a naturally occurring signalling peptide. It acts in the laboratory as a non-selective melanocortin receptor agonist, engaging receptors in the melanocortin family.
Why Researchers Study It
Because it activates melanocortin receptors, Melanotan II is used in laboratory models of melanogenesis (pigmentation) signalling and melanocortin-receptor pharmacology. This is experimental, in-vitro characterisation only.
How It Is Characterised in the Lab
Identity and quality are confirmed analytically rather than assumed. A credible research supply confirms identity by mass spectrometry (MS) and purity by HPLC — typically 99%+ — through an accredited (ISO 17025) third-party laboratory, with a per-batch Certificate of Analysis (COA) tied to the exact lot. The CAS reference is 121062-08-6.
