PT-141 10 mg

PT-141 peptide, also known as Bremelanotide, is a synthetic cyclic heptapeptide derived from α-melanocyte-stimulating hormone (α-MSH). This PT-141 peptide functions as a melanocortin receptor agonist with primary activity at MC3R and MC4R within the central nervous system, modulating neural circuits involved in sexual arousal and motivation independently of peripheral vascular pathways.

Unlike conventional compounds that act through nitric oxide or phosphodiesterase-5 (PDE5) pathways, PT-141 targets central melanocortin signaling, making it a distinct research tool for studying neuroendocrine regulation of sexual behavior and motivation. Experimental data indicate a relatively rapid onset of activity following administration, along with generally favorable tolerability profiles in controlled research settings (Diamond et al., 2004 — Journal of Sex & Marital Therapy).

Further preclinical and clinical investigations have explored PT-141's interaction with the melanocortin system across both male and female research models, positioning it as a valuable compound for neuroendocrine and behavioral pharmacology research (Safarinejad & Hosseini, 2008 — Journal of Urology).

The peptide is supplied as a lyophilized powder to ensure optimal stability during storage and handling.
