PT-141

PT-141, also known by its research name Bremelanotide, is a synthetic peptide derived from the melanocortin family of peptides. Originally developed from the base structure of Melanotan II, PT-141 is distinct in its targeted interaction with melanocortin receptors MC3R and MC4R, which are involved in the central nervous system and are thought to play a role in various behavioral and regulatory mechanisms.

Researchers have shown growing interest in PT-141 due to its ability to influence melanocortin signaling pathways, particularly those associated with neurological and behavioral studies. Unlike many peptides that affect the peripheral vascular system, PT-141’s mechanism is centered on the neurological modulation of specific receptors, providing a unique angle for laboratory studies investigating brain-receptor interactions.

Each vial of PT-141 offered by Lifestyle Peptides contains 10mg of lyophilized (freeze-dried) powder, manufactured under strict quality controls in a certified, U.S.-based facility. The peptide is produced with a purity level exceeding 98.5%, ensuring consistency and reliability in experimental settings.

Research Applications

PT-141 has been utilized in scientific studies that investigate the role of melanocortin receptors in behavioral regulation, particularly in the hypothalamic-pituitary-adrenal (HPA) axis. The peptide’s influence on MC3R and MC4R receptors has been explored in a variety of laboratory models related to mood, motivation, and energy balance. Due to its selectivity for central rather than peripheral receptors, PT-141 is an important candidate for exploring the intersection of peptide signaling and neurological activity.

Some research has also explored how PT-141 interacts with various hormonal systems and neurotransmitter pathways, making it a popular subject in neuroscience and behavioral pharmacology labs. However, it’s important to emphasize that PT-141 is not approved by the FDA for any human use and should be handled strictly according to research use protocols.

Handling & Reconstitution

PT-141 is supplied in lyophilized powder form to preserve stability and extend shelf life. Reconstitution should be performed in a sterile laboratory environment using bacteriostatic water or another appropriate sterile diluent. Reconstituted solutions are not stable indefinitely and should be used immediately or stored in aliquots to avoid multiple freeze-thaw cycles.
