Melanotan 2 (MT-2): What the Research Says
Melanotan 2, or MT-2, is one of the most well-known melanocortin peptides in research, and it is frequently compared with its more selective cousin Melanotan 1. This overview explains what MT-2 is and what the research describes, strictly for educational and research context.
What MT-2 actually is
MT-2 is a synthetic analogue of alpha-melanocyte-stimulating hormone (α-MSH). Unlike the more selective Melanotan 1, MT-2 is a non-selective melanocortin agonist: it activates several melanocortin receptors, including MC1R (pigmentation) and MC4R (which is involved in other pathways).
What the research explores
Because of its broader receptor activity, MT-2 has been studied for melanogenesis (the pigmentation pathway) as well as effects linked to MC4R activation. Notably, the research compound PT-141 (bremelanotide) was derived from MT-2, isolating the MC4R-related activity — a good example of how studying one peptide leads to another.
Handling and preparation
MT-2 is supplied as a lyophilised powder, kept cold and protected from light, then reconstituted for laboratory work. Our reconstitution guide and the on-site peptide calculator walk through preparing a solution and calculating concentration. Every batch ships with a per-batch Certificate of Analysis.
Important context
This article summarises published research for educational purposes only. MT-2 is supplied strictly for laboratory and research use only — not for human or veterinary use, consumption, or injection. Nothing here is medical advice, a recommendation, or a dosing protocol.
The bottom line
MT-2 is a non-selective melanocortin agonist studied for melanogenesis and MC4R-related pathways, and the parent compound from which PT-141 was derived. As with everything we carry, our MT-2 comes with full batch documentation and a verifiable COA.
