PT-141 (Bremelanotide) — Melanocortin Receptor Agonist Research Peptide
PT-141, also known as Bremelanotide, is a synthetic cyclic heptapeptide developed as a melanocortin receptor agonist. It was derived from the parent compound Melanotan II through structural modification, and is one of the more extensively researched compounds in the melanocortin receptor pharmacology category.
Mechanism of Action
PT-141 has been investigated in published research for activity across several biological pathways, including:
- MC3R and MC4R receptor agonism — binding to the melanocortin-3 and melanocortin-4 receptors, two members of the melanocortin receptor family expressed in the central nervous system
- Central nervous system signaling — research on hypothalamic and limbic-system pathways downstream of melanocortin receptor activation
- cAMP signaling pathways — investigations into the second-messenger signaling cascades activated by MC3R/MC4R binding
- Comparative melanocortin research — comparative studies against the parent compound Melanotan II and other melanocortin receptor ligands
PT-141 is distinguished in melanocortin research literature from its parent compound Melanotan II by structural modifications that alter its receptor selectivity profile and pharmacokinetic characteristics.
Research Applications
PT-141 is widely used in research contexts including:
- Melanocortin receptor pharmacology and selectivity studies
- MC3R and MC4R receptor binding and signaling research
- Central nervous system melanocortin pathway research models
- cAMP and G-protein-coupled receptor signaling research
- Comparative analysis against Melanotan II and other melanocortin family ligands

Reconstitution & Storage
Lyophilized PT-141 should be stored at -20°C for long-term stability and protected from light. Once reconstituted with bacteriostatic water, the solution should be refrigerated at 2–8°C and used within the timeframe indicated on the product COA. Avoid repeated freeze-thaw cycles, as they can degrade peptide integrity.
Shipping & Handling
All orders are shipped with temperature-controlled packaging to preserve peptide integrity. Domestic orders typically arrive within 2–4 business days. Tracking is provided on every order.

Storage & Handling
Proper storage and handling are essential to maintaining peptide stability and ensuring the integrity of your research material.
Storage Recommendations
Lyophilized peptides should be stored at -20°C for long-term preservation. For short-term storage of up to 30 days, refrigeration between 2-8°C is acceptable. Reconstituted peptides should always be refrigerated and used within 30 days.
Avoid the following:
Direct sunlight or UV exposure Repeated freeze-thaw cycles Temperature fluctuations Storage at room temperature beyond brief handling periods
Reconstitution Best Practices
Allow vials to reach room temperature before opening to prevent condensation. Use bacteriostatic water as the diluent for most peptides, injecting slowly along the side of the vial. Gently swirl to dissolve — do not shake. Allow the solution to fully dissolve before drawing for research use.
Shelf Life
Lyophilized peptides maintain potency for up to 24 months when stored properly at -20°C. Reconstituted solutions should be used within 30 days for optimal research results.
