PT-141 (Bremelanotide) for Melanocortin Research
Technical Overview
PT-141, also known as bremelanotide, is a synthetic peptide derived from the alpha-melanocyte-stimulating hormone (α-MSH) family. Researchers study it for its role in sexual function and arousal through activation of melanocortin receptors, and for its broader role in neuroendocrine regulation.
Research applications
- Sexual health research: how melanocortin receptor activation influences arousal and responsiveness.
- Vascular research: its role in blood flow in sexual function studies.
- Neuroendocrine regulation: pathways linked to mood, stress response and behavior.
- Energy balance and inflammation: its effects on energy regulation, appetite and inflammatory processes.
Mechanisms under study
Scientists explore how PT-141 interacts with the melanocortin-4 (MC4) receptor, which plays a key role in sexual arousal and energy balance, and how it influences central nervous system pathways that affect both physical and emotional well-being. This makes it a focus of research on sexual dysfunction, mood regulation and stress-related conditions.

Storage Instructions
Handling and Storage Tips:
- On arrival, store the sealed vial at −20 °C, protected from light and moisture.
- For short-term storage (days to weeks), refrigeration at 2–8 °C is acceptable.
- Lyophilized peptides tolerate room temperature for short periods, such as during shipping.
- Let the vial reach room temperature before opening, to avoid condensation.
- Once reconstituted, keep refrigerated at 2–8 °C and avoid repeated freeze–thaw cycles.
