The Solira Take

PT-141 (Bremelanotide) is a melanocortin-receptor agonist heptapeptide, derived as a metabolite of Melanotan II. Characterized in preclinical research on MC3R / MC4R signaling pathways.

COA / Testing

Every batch of product sold by Solira undergoes independent third-party analytical testing to verify identity and purity, performed by Chromate.

  • HPLC purity analysis — confirms compound purity
  • Mass spectrometry — identity confirmation via molecular weight verification
  • Lot-specific documentation — each COA corresponds to the specific manufacturing lot

COA available upon request. Contact us for lot-specific documentation.

Description

PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide analogue of α-MSH. It differs from Melanotan II by the absence of a C-terminal amide. Supplied as lyophilized powder for laboratory research.

Supplied for in vitro research and preclinical investigation only. Independently verified by HPLC and mass spectrometry.
