PT-141 Peptide for Sale – PT-141 Peptide (Bremelanotide) – High Purity ≥99% | cGMP Grade for Sexual Behavior & Melanocortin Research

PT-141 Peptide (Bremelanotide) is a synthetic 7-amino acid cyclic peptide lactam that functions as a potent, non-selective melanocortin receptor agonist. It is derived from the core structure of alpha-melanocyte-stimulating hormone (α-MSH) with enhanced stability and bioavailability.

PT-141 exhibits high affinity for melanocortin receptors MC3R and MC4R, which are expressed extensively in the central nervous system, particularly in the hypothalamus. Activation of MC4R is associated with sexual behavior modulation, erectile function, and female sexual arousal responses.

Looking for PT-141 peptide for sale from a trusted supplier? Shanghai AmbioPharm, Inc. offers high purity PT-141 peptide manufactured under advanced, quality-controlled environments to support modern research applications. PT-141, also known as Bremelanotide in scientific literature, is widely studied in peptide and biochemical research, making it a valuable compound for laboratory and biotech use.

Our PT-141 peptide is synthesized using pharmaceutical-grade processes to ensure ≥99% purity, stability, and consistent batch performance. Each order includes a Certificate of Analysis (COA), providing full transparency and verification of product quality. With our manufacturing facility in Shanghai and USA-based distribution support, we ensure fast, secure shipping and reliable supply for both small-scale and bulk orders.

Unlike peripherally acting agents, PT-141 acts centrally within the brain to initiate sexual response pathways, independent of psychogenic or vascular mechanisms. This unique mechanism distinguishes it from other research compounds in sexual behavior studies.

At Shanghai AmbioPharm, Inc., we supply high-purity PT-141 Peptide (≥99% by HPLC) for advanced melanocortin and sexual behavior research. Our cGMP-grade material is synthesized in our FDA-inspected Shanghai facility and available for fast U.S. delivery from our Clearwater, South Carolina warehouse.

Mechanism of Action:
PT-141 crosses the blood-brain barrier and activates melanocortin-4 receptors (MC4R) in the paraventricular nucleus (PVN) of the hypothalamus. MC4R activation triggers downstream signaling via Gs proteins and cAMP production, leading to neuronal activation of oxytocinergic pathways. This central melanocortin pathway initiates pro-erectile and pro-sexual behavioral responses independent of peripheral vascular mechanisms.

 Intended Use: For laboratory research purposes only. Not for human consumption or clinical use without regulatory approval.
