PT-141: Research Profile, Dosages & Supplier Prices
PT-141 is a melanocortin research compound with a molecular weight of 1025.2 g/mol and a research half-life of approximately 2-3 hours in published human pharmacokinetic data. PT-141 (bremelanotide) is a cyclic melanocortin peptide derived from Melanotan II research, developed to isolate MC4R-mediated effects. It is the active ingredient in Vyleesi, an FDA-approved drug - making it one of the few research peptides with full human clinical trial data behind it.

What is PT-141?
Research interest centers on melanocortin-4 receptor pharmacology and central nervous system pathways, which are distinct from the vascular mechanisms of PDE5 inhibitors.
In the RUO market, PT-141 is a straightforward synthesis and generally inexpensive. Quality differentiators are purity and accurate filling rather than exotic manufacturing.
Mechanism of Action (Research Context)
Melanocortin receptor agonist with preference for MC4R in the central nervous system, studied for centrally-mediated pathways rather than vascular mechanisms.
