What Is PT-141?

PT-141 (Bremelanotide) is a cyclic heptapeptide metabolite of Melanotan II, formed via removal of the C-terminal amide group. It acts as a melanocortin receptor agonist with preferential activity at MC3R and MC4R over MC1R — distinguishing it from its parent compound's non-selective receptor profile. This selectivity is the primary research rationale for using PT-141 over Melanotan II when studying MC3R or MC4R-driven pathways in isolation.

Preclinical research has examined PT-141 in sexual function models (MC4R), appetite and energy homeostasis (MC3R/MC4R), and inflammatory response pathways. The reduced MC1R activity means melanogenesis is a less confounding variable in MC3R/MC4R research designs. Eternal Peptides Wholesale stocks both PT-141 (PT10) and Melanotan II (MT10) for comparative receptor research.

For non-selective melanocortin receptor research, see Melanotan II (MT10). For research use only.

Frequently Asked Questions

Where can I buy PT-141 in Australia? +

Eternal Peptides Wholesale is an Australian-owned, ABN-registered distributor supplying PT-141 for research purposes. PT10 (10mg, box of 10) is $544.50. Janoshik-verified, dispatched from Australia within 1-2 business days. For research use only.

How does PT-141 differ from Melanotan II? +

MT-II activates MC1R, MC3R, MC4R, and MC5R. PT-141 is its metabolite with reduced MC1R affinity, enabling more selective MC3R/MC4R research with less confounding melanogenesis. Both are available from Eternal Peptides. See the Melanotan II page. For research use only.

How is PT-141 quality verified? +

Every batch is tested by Janoshik Analytical — HPLC purity, mass spectrometry identity, sterility (USP), endotoxin (LAL), heavy metals (ICP-MS). COA published and independently verifiable at janoshik.com. For research use only.

How quickly is PT10 dispatched? +

Orders dispatched within 1-2 business days of payment confirmation from Australia. COA included with every order.
