See all certificates of analysis Storage & handling Peptides require cold-chain handling to preserve integrity throughout your research timeline. Before reconstitution: Store the lyophilized vial frozen at -20 °C, protected from light and moisture. After reconstitution: Keep refrigerated at 2–8 °C and use within 4 weeks. Do not freeze the reconstituted solution. Sterile sealed glass vial to maintain integrity in transit and storage. Diluent and laboratory supplies are not included and must be sourced separately for research. Sourcing & quality Why source Semax from Sports Technology Labs Research peptides vary widely in identity, purity, and actual peptide content between suppliers, which makes independent third-party verification by HPLC and mass spectrometry essential. Sports Technology Labs publishes its certificates of analysis on the website. 99.00%verified batch purity (HPLC) ≥98%minimum purity specification 10 mgpeptide per lyophilized vial -20 °Cfrozen storage before reconstitution Third-party tested & certified Identity, purity, and concentration verified by MZ Biolabs (Tucson, AZ), an accredited US laboratory. Lyophilized & cold-stored Vials are freeze-dried and kept frozen to help preserve peptide stability. Sterile glass vials, packaged in America Accurate, verifiable specifications with no discreet payment methods or mislabeling. 60-day money-back guarantee Transparent business, standard payment methods, no misrepresentation. Research context What is Semax? Semax is a synthetic heptapeptide — a chain of 7 amino acids with the sequence Met-Glu-His-Phe-Pro-Gly-Pro. It is derived from the 4-10 fragment of adrenocorticotropic hormone (ACTH), with an added C-terminal Pro-Gly-Pro tripeptide extension that increases resistance to enzymatic degradation compared to the unmodified ACTH fragment (ref. 1). It is produced synthetically for laboratory use. Semax is an experimental research compound supplied strictly for laboratory research. Sports Technology Labs makes no claims regarding its effects, and nothing in this listing should be interpreted as describing outcomes in humans or animals. Regulatory & compliance status Important regulatory information Not approved for human use Semax has a Russian regulatory approval for stroke recovery and cognitive impairment, but is not approved by the FDA or any equivalent US regulatory body. It is not a dietary supplement, drug, or food in the United States, and marketing it for human ingestion here is unlawful. Anti-doping status Semax is not individually named on the current WADA Prohibited List, but as a substance without FDA, EMA, or equivalent approval outside Russia, it falls under the S0 (Non-Approved Substances) catch-all. Legal status for research In the United States, Semax is not a scheduled or controlled substance and may be legally purchased and possessed for laboratory research use. Our position Sports Technology Labs are chemical suppliers, not medical providers. We do not condone or encourage consumer use of research compounds.
