Alpha-MSH (alpha-melanocyte stimulating hormone) is a 13-amino-acid melanocortin peptide derived from pro-opiomelanocortin, acting on melanocortin receptors to regulate pigmentation, inflammation, appetite and energy homeostasis in research models. It is supplied as a high-purity white lyophilized powder at >=99% HPLC purity in sealed vials, offering good stability and easy reconstitution. It is used in melanocortin receptor studies, anti-inflammatory research, pigmentation biology and metabolic experiments, and is a common reference compound in endocrine laboratories. Quality control is performed on each batch with batch COA available on request. Keep the product sealed at 2-8 degree C, protected from light and moisture; for long-term storage -20 degree C is recommended and repeated thawing should be avoided. We accept both sample and bulk orders, offer OEM and private label service, and arrange discreet neutral packing for worldwide shipping.
