Semax is a synthetic regulatory heptapeptide derived from the adrenocorticotropic hormone fragment ACTH 4-10, with the sequence Met-Glu-His-Phe-Pro-Gly-Pro, studied in cognitive and neuroprotective research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. Semax is investigated in research on neural protection, learning and memory, cognitive function and neuropeptide signaling, and is commonly applied in cell-based and preclinical neuroscience studies. The freeze-dried form provides good stability and reproducible reconstitution for consistent experimental dosing. Each production batch is tested for purity and batch COA is issued upon request. Store the sealed vial at 2-8 degree C, protected from light and humidity; for extended storage -20 degree C is recommended with limited freeze-thaw cycles. Trial orders and bulk supply are both accepted, with OEM and private-label service and discreet neutral packing for worldwide shipping. Research use only, not for human or veterinary application.
