What is PT-141 (Bremelanotide)?
PT-141 (bremelanotide) is a synthetic cyclic heptapeptide and melanocortin receptor agonist. Laboratory literature examines its receptor-binding profile and downstream signalling across the melanocortin system.
Research focuses especially on MC3R and MC4R activity, receptor selectivity, ligand-response relationships, and signalling measurements. This listing describes the compound and those pathway-level endpoints only.
The pre-formulated research solution is listed separately as Nasal PT-141.

PT-141 research questions
+What is PT-141 (bremelanotide)?
PT-141, also called bremelanotide, is a synthetic cyclic heptapeptide melanocortin receptor agonist supplied as laboratory research material.
+Which receptors are examined in PT-141 research?
Published laboratory literature examines PT-141 activity across melanocortin receptors, with particular attention to MC3R and MC4R signalling and receptor-selectivity measurements.
+How does PT-141 differ from MT-2?
Both are melanocortin analogs, but PT-141 is generally examined for its relative MC3R and MC4R activity, while MT-2 is studied across a broader melanocortin-receptor profile.
+Is a PT-141 COA on file?
Yes. A Janoshik Analytical report dated June 2026 is on file for PT-141 10 mg vial material. Match the batch identifier on the received material to the public COA lookup.
+What purity specification applies to PT-141?
The listed purity specification is ≥99%. The batch identifier should be used to locate the corresponding analytical documentation.
+What format is supplied?
PT-141 is supplied as 10 mg of lyophilized research material in a sealed vial. Current pricing and availability appear on this page.
+How should sealed PT-141 research material be stored?
Keep the sealed vial refrigerated, dry, protected from light, and within the conditions stated in its batch documentation.
