PT-141 (Bremelanotide) is a synthetic cyclic peptide that acts as a melanocortin receptor agonist. It is studied in research settings investigating central nervous system pathways related to arousal, distinct from the peripheral vascular mechanisms studied with other compound classes.

Each vial is lyophilized and shipped with a batch-specific Certificate of Analysis confirming purity via HPLC and mass spectrometry.

Storage: Store lyophilized peptide refrigerated (2–8°C) prior to reconstitution; use bacteriostatic water for reconstitution.
