Description
PT-141 Research Peptide
PT-141 is a synthetic cyclic peptide analog of alpha-melanocyte-stimulating hormone, commonly referred to as α-MSH. It is used in controlled laboratory research involving melanocortin receptor interaction models, peptide-receptor binding dynamics, intracellular signaling pathway analysis, and structure-function characterization.
ResearchChemHQ supplies PT-141 in lyophilized powder form to support stability during shipping, storage, and laboratory handling. Each batch is produced for research-use-only applications and may be supported by batch-specific documentation through the RCHQ COA Library.
PT-141 is intended strictly for laboratory, analytical, and scientific research use only. It is not intended for human or animal consumption, medical use, diagnostic use, therapeutic use, dietary supplement use, cosmetic use, or compounding.

Storage and Handling
Store lyophilized PT-141 according to proper laboratory storage practices.
- Keep lyophilized material in a cool, dry environment
- For long-term storage, maintain at -20°C / -4°F
- Once reconstituted, store at 2–8°C / 36–46°F
- Use promptly after reconstitution according to internal laboratory protocols
- Maintain aseptic handling practices
- Avoid repeated freeze-thaw cycles
- Protect from unnecessary light, heat, and moisture exposure
Storage conditions may affect peptide stability, so researchers should follow appropriate handling standards for lyophilized peptides.
