Semax is an ACTH-derived heptapeptide studied in laboratory models of neurotrophic signaling and cognition.
Published preclinical studies have examined Semax in the context of:
These represent areas of active laboratory investigation. Findings from animal and cell-culture models do not establish safety or efficacy in humans, and Semax is not an approved product for any human use.
Supplied as a lyophilized powder, Semax is stored at −20°C when kept desiccated and protected from light. Once reconstituted with bacteriostatic water, it should be kept at 2–8°C and used within a research-appropriate timeframe. See the reconstitution calculator for concentration and draw-volume math, and the handling & storage guide for shelf-life sourcing (USP <797>).

Yes. Every lot is analyzed by an independent third-party laboratory using HPLC for purity and mass spectrometry for identity confirmation. The Certificate of Analysis for your specific lot is published and available before purchase.
Store the lyophilized powder at −20°C, desiccated and away from light, where it is stable long-term. After reconstitution with bacteriostatic water, keep refrigerated at 2–8°C and use within a research-appropriate window.
Semax is sold exclusively for laboratory and scientific research use. It is not a drug, dietary supplement, or food, and it is not intended for human or veterinary use, consumption, or administration of any kind.
Orders are processed and shipped domestically within the United States, typically arriving in 2–4 business days. Compounds are packaged to protect the lyophilized powder in transit.
