PT‑141 10mg

PT‑141, also known as Bremelanotide, is a synthetic peptide derived from the melanocortin pathway. Unlike earlier melanocortin analogues, PT‑141 acts primarily as a melanocortin‑4 receptor (MC4R) agonist, making it a valuable research tool for studying neuroendocrine signalling, sexual behaviour pathways, and central melanocortin activity. This compound is ideal for controlled laboratory studies requiring precision, purity, and reproducibility.

Why Is PT‑141 of Interest to the Research Community?

PT‑141 is a potent agonist of the melanocortin‑4 receptor (MC4R), a key receptor involved in regulating sexual behaviour, appetite, and neuroendocrine signalling. Unlike PDE‑based compounds, PT‑141 acts centrally rather than peripherally, making it a unique tool for studying brain‑mediated pathways.

Key areas of scientific interest include:

• Neuroendocrine signalling — PT‑141 influences hypothalamic pathways involved in arousal and behavioural responses.
• Melanocortin system research — MC4R is central to appetite, energy balance, and autonomic regulation.
• Sexual behaviour studies — PT‑141 is widely used to explore central mechanisms of libido and arousal.
• Stress and reward pathways — melanocortin receptors interact with dopaminergic and limbic systems.
• Comparative studies with α‑MSH analogues — PT‑141 is a derivative of Melanotan II with improved receptor selectivity.

PT‑141’s central mechanism of action makes it a valuable compound for neuroscience, behavioural biology, and endocrine research.
