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. Semax is used in cognition and neuroprotection work where the design combines behavioral readouts with biochemical markers, and investigators measure memory performance, anxiety-like behavior and plasticity endpoints in rodent models over repeated dosing days. Its defined heptapeptide sequence keeps synthesis reproducible, and the lyophilized form supports accurate reconstitution for each treatment session. Our records verify purity per batch, and we can supply matched lots so behavioral scores are not confounded by material differences between groups. A small dilution volume gives the working concentration, and the included notes specify storage for the repeated dosing days used in behavioral work. Because cognitive scores are sensitive to material differences, we can supply matched lots for the whole cohort. Trial and bulk quantities are available, with packing that protects the peptide during shipping. With a stable supply chain and strict quality control, we serve research teams and distributors in many countries. Every parcel is professionally packed and tracked, and we provide timely communication from order to delivery, plus after-sales support.
