The dosage and frequency of administration should be determined by a healthcare professional based on individual research goals
PT-141, measured in a single radioligand displacement series against I-NDP-alpha-MSH on membranes from BHK570 cells stably expressing each human subtype, returned Ki 0.25 nM at MC4R, 6.4 nM at MC1R, 17 nM at MC5R and 53 nM at MC3R, roughly 26-fold, 68-fold and 210-fold preference for MC4R over MC1R, MC5R and MC3R respectively
