Bremelanotide, also known as PT-141, is a synthetic cyclic peptide analogue of alpha-melanocyte-stimulating hormone studied in melanocortin receptor research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. Bremelanotide is investigated in research on melanocortin receptor signaling and related receptor pathways, and is commonly applied in cell-based and preclinical studies. The freeze-dried presentation provides excellent stability and reproducible reconstitution for consistent experimental dosing. Each batch is manufactured under controlled quality systems and batch-specific certificates of analysis are obtainable on request. Store the sealed vial at 2-8 degree C away from direct light and humidity; for extended storage keep at -20 degree C and minimize freeze-thaw cycles. Small sample orders and bulk quantities are both welcomed, and we provide OEM, private-label and secure neutral-packaging services for global delivery. Laboratory research use only.
