Melanotan II Research Profile

Melanotan II (MT-II) is a cyclic lactam analogue of alpha-melanocyte-stimulating hormone (alpha-MSH), designed as a non-selective melanocortin receptor agonist with activity at MC1R, MC3R, MC4R, and MC5R. It has been studied in research models of skin pigmentation via MC1R activation, sexual function via MC4R central pathways, appetite suppression, and metabolic regulation. PT-141 (Bremelanotide) is a derivative of Melanotan II developed to selectively target central melanocortin pathways with reduced melanotropic activity. CAS: 121062-08-6. Molecular weight: 1024.2 g/mol.

Frequently Asked Questions

Q: What is Melanotan II studied for in research?
A: Melanotan II is investigated in research models covering MC1R-mediated pigmentation, MC4R central sexual function pathways, appetite suppression, and melanocortin system pharmacology. For research use only.

Q: How does Melanotan II differ from PT-141?
A: Melanotan II is a non-selective melanocortin agonist active at MC1R, MC3R, MC4R and MC5R. PT-141 is a cyclic derivative with reduced MC1R activity, designed to focus on central MC3R/MC4R pathways. PT-141 produces less pigmentation effect in research models.

Q: What purity does Official Peptides supply for Melanotan II?
A: All Melanotan II from Official Peptides is third-party HPLC-verified at >99% purity with a batch-specific COA included with every order.
