PT-141, also called Bremelanotide, originated from Melanotan 2 research at the University of Arizona. Scientists there were characterizing melanocortin receptor analogs and observed MC4R-mediated signaling activity distinct from the melanogenesis pathways that were the original focus of investigation.
Researchers subsequently modified the Melanotan 2 structure to produce a cyclic heptapeptide with altered receptor selectivity. The resulting compound, PT-141, has since appeared in peer-reviewed preclinical and clinical publications examining melanocortin receptor binding and central nervous system signaling.
Bremelanotide has been the subject of published clinical pharmacology investigations. The research-grade form is used in melanocortin receptor signaling studies. This product is intended for research use only.
Tissue Regeneration Research
Investigated in preclinical models for its effects on muscle, tendon, and ligament tissue repair mechanisms.
Wound Healing Research
Examined in animal wound models for observations related to tissue closure and ulcer repair pathways.
Anti-inflammatory Research
Studied in laboratory research for interactions with inflammation-related signaling pathways across various tissue types.
Gastrointestinal Research
Evaluated in preclinical GI tissue models for observations related to gastric and intestinal mucosal integrity.
All of our products are manufactured using the Lyophilization (Freeze Drying) process, which ensures that our products remain 100% stable for shipping for up to 3-4 months. Once the peptides are reconstituted (mixed with bacteriostatic water), they must be stored in the fridge to maintain stability. After reconstitution, the peptides will remain stable for up to 30 days.
Reconstitute slowly by adding solvent to the side of the vial and allowing it to dissolve without agitation. Do not shake. Store away from direct light. All products are shipped with dry ice or cold packs to maintain cold-chain integrity.
All PT-141 batches are independently tested by a third-party laboratory for purity and identity verification via HPLC with UV detection coupled with Mass Spectrometry.
