About PT-141
PT-141, also known as bremelanotide, is a cyclic heptapeptide melanocortin receptor agonist. It is closely related in structure to Melanotan 2.
PT-141 acts mainly at the MC3R and MC4R receptors and has been studied in research on central melanocortin signaling.
Each vial contains 10mg of lyophilized powder. The current lot was tested by an independent lab for HPLC purity, net content and endotoxin. Match the batch number on your label to its report in our COA library.
Every tested lot has its COA published under the batch number on your label. For laboratory research use only.

HPLC purity is the share of the sample measured as PT-141; on its own it doesn't confirm identity or sterility. The endotoxin screen is a pass or fail against the lab's limit for bacterial endotoxin, not a statement about safety or effects.
