PT-141: Research Background

Mechanism of Action: PT-141 (Bremelanotide) is a cyclic heptapeptide melanocortin receptor agonist derived from Melanotan II. It activates MC3R and MC4R receptors in the central nervous system, influencing sexual function pathways through dopaminergic and oxytocinergic signaling.

Research Applications: Central nervous system melanocortin signaling, sexual function research, MC3R/MC4R receptor biology, and hypothalamic pathway modulation studies.

Published Research: Shadiack et al. (2007) on bremelanotide mechanism. FDA-approved formulation studies (Vyleesi) in Journal of Sexual Medicine. PubMed: ‘bremelanotide melanocortin’.

Storage & Reconstitution

Storage: Store lyophilized peptide at -20°C. After reconstitution, refrigerate at 4°C and use within 28 days.

Reconstitution Protocol: Add 2ml bacteriostatic water per 10mg vial. Inject slowly along vial wall. Swirl gently.
