PT-141

Investigating Neuroendocrine and Melanocortin Receptor Pathways

PT-141, also known as Bremelanotide, is a synthetic peptide analog of alpha-melanocyte-stimulating hormone (α-MSH). It has become a focal point in neuroendocrine and melanocortin receptor research, particularly for its ability to bind to MC3R and MC4R receptors—both of which play critical roles in the regulation of mood, behavior, and sexual function in laboratory models.

In preclinical and in vitro studies, PT-141 has been used to explore CNS signaling, dopaminergic modulation, and peptide-hormone interaction dynamics. Unlike compounds that act directly on the vascular system, PT-141 operates through neural pathways, making it a unique research tool for scientists studying behavioral neuroscience, hypothalamic function, and central nervous system peptide signaling.

Why Researchers Study PT-141

• Targets melanocortin receptors (MC3R/MC4R) in lab models

• Studied in relation to neuroendocrine signaling and behavioral response

• Explored in preclinical studies for CNS peptide modulation

• Unlike PDE-based models, PT-141 affects neural rather than vascular pathways

• A growing focus in sexual health and hypothalamic function research environments

At Lifestyle Peptides, we provide high-purity PT-141 in lyophilized form for laboratory research use only. All compounds are produced under GMP-aligned conditions, batch-tested for identity and purity (≥98%), and shipped in sterile, sealed vials. PT-141 is not approved for human or veterinary use, and must not be used in any way outside of controlled scientific environments.
