PT-141

PT-141 is a stabilised cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone. Published pharmacology characterises it as a non-selective melanocortin receptor agonist with the studied activity attributed largely to MC3R and MC4R, receptors expressed predominantly in the central nervous system rather than peripheral tissue. This vial is supplied as a lyophilised powder, which is the format most laboratory protocols specify because the dry peptide is stable at -20°C and the researcher controls the final concentration. Reconstitute with bacteriostatic water down the inside wall of the vial, swirl rather than shake, and calculate concentration from the 10 mg vial mass using our reconstitution calculator. Each batch carries a reference that can be matched against the record on our lab results page. For research purposes only, not for human consumption.
