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. Cognitive research groups typically combine behavioral scoring with plasticity and stress markers in rodent models, and Semax is dosed over repeated days from freshly prepared lyophilized stock so each session uses identical material. The heptapeptide sequence keeps synthesis reproducible, and our records verify purity per batch. Matched lots can be reserved for the whole cohort, with delivery arranged to preserve handling conditions throughout. Each batch of Semax is released with its purity certificate, and the lyophilized peptide is easy to prepare for the repeated dosing cognitive studies use. Behavioral protocols benefit from one-lot supply, so we can reserve a single lot for the cohort and coordinate delivery within recommended conditions. Bulk options are available. Orders are processed promptly after confirmation, with professional packaging that protects lyophilized material during transit. We support both trial quantities for evaluation and bulk volumes for ongoing research programs, with dedicated after-sales assistance at every step.
