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. Every batch is quality-controlled and batch-specific COA can be supplied on request. Unopened product should be kept sealed at 2-8 degree C away from light and moisture, with -20 degree C recommended for long-term storage. We accept both trial and bulk orders, and OEM and private-label service is available. This peptide is for laboratory research use only, not for human or veterinary purposes.
