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. Strict quality control is applied to every batch, and COA is available for specific batches on request. Keep the unopened product sealed at 2-8 degree C away from light; -20 degree C is recommended for long-term storage avoiding repeated thawing. Small and bulk orders are both welcome, and OEM and discreet neutral packing are offered. For laboratory research use only, not for human or veterinary application.
