PT-141 (Bremelanotide) is a synthetic peptide analog of α-MSH studied in research for its role in melanocortin receptor pathways, particularly MC3R and MC4R signaling cascades. This cyclic heptapeptide compound has been investigated for its interactions with central nervous system melanocortin receptors and associated neurochemical processes in laboratory settings.
Research studies have examined PT-141’s mechanism of action through melanocortin receptor activation, exploring its influence on hypothalamic signaling pathways and neurotransmitter modulation. The compound’s unique cyclic structure and receptor selectivity profile make it a valuable tool for researchers investigating melanocortin system biology and related physiological processes.
Each 10mg vial contains high-purity PT-141 (Bremelanotide) in lyophilized powder form, manufactured under strict quality control standards. This compound is sourced from the same supplier as our verified catalog, but the current batch has not yet completed Janoshik Analytical’s independent “Match-Batch” testing.
