Melanotan I — also written Melanotan 1 or abbreviated MT-1 (afamelanotide, CAS 75921-69-6, molecular formula C78H111N21O19) — is a synthetic analogue of alpha-melanocyte-stimulating hormone (alpha-MSH) studied for its interaction with melanocortin receptor pathways, particularly the MC1R receptor. PhaseOne supplies Melanotan I to researchers across Australia as a high-purity lyophilised powder, independently HPLC verified at ≥99% purity per batch.
As a first-generation melanocortin analogue, Melanotan 1 is studied alongside its structural relative Melanotan II within Australian peptide research, manufactured to research-grade standards and independently third-party tested for identity and consistency, with every order shipped Australia-wide.

Melanotan I — also called Melanotan 1 or MT-1 (afamelanotide) — is a synthetic analogue of alpha-melanocyte-stimulating hormone (alpha-MSH), studied for its interaction with melanocortin receptors, particularly MC1R, within Australian peptide research.
Melanotan I (MT-1) is a linear first-generation alpha-MSH analogue studied for more selective melanocortin activity, whereas Melanotan II is a cyclic analogue studied for broader melanocortin receptor activity; the two have distinct structures and research profiles. (!) View our Melanotan II.
Unreconstituted Melanotan I should be stored refrigerated and protected from light, and is commonly reconstituted with bacteriostatic water prior to research preparation. (!) Read our reconstitution guide.
Each PhaseOne batch is independently verified by third-party HPLC analysis, with a Certificate of Analysis available for every order shipped across Australia.
Melanotan I is studied within the melanocortin and cosmetic-adjacent peptide research category. (!) Explore our cosmetic peptide guide.
