Research-Grade Compound
Semax Nasal Spray is an intranasal laboratory presentation of Semax, a short synthetic peptide analogue drawn from the adrenocorticotropic hormone (ACTH) fragment family and described in the peptide literature as a putative cognitive enhancing neuropeptide. It is supplied strictly for in-vitro and non-human laboratory research, either as a solution held in a spray actuator or as lyophilized material packaged alongside an unfilled actuator body.
For laboratory research use only. Not for human or veterinary use.
Purity standard: Semax Nasal Spray is sourced to ≥99% by HPLC — sourcing spec.
For laboratory research use only. Not for human or veterinary use.

Buying Semax Nasal Spray — Frequently Asked Questions
What purity standard applies?
The sourcing standard is >=99% by HPLC. That is a specification the material is procured against, not a measured figure for the vial in your hand; the measured number for your specific lot appears on that lot's Certificate of Analysis.
What documentation ships with an order?
A lot-specific Certificate of Analysis with the HPLC chromatogram and mass spectrometry identity confirmation for that lot. Requesting and archiving that document alongside your raw data is the practical answer to identity uncertainty in this compound class, which analytical work on seized preparations has repeatedly flagged as a real problem.
How should the material be stored?
Hold lyophilized material at -20 degrees Celsius, desiccated and dark. Once in solution, keep it at 2 to 8 degrees Celsius, protected from light, and work through it promptly. Aliquot before freezing rather than freezing and thawing one vial repeatedly.
Is Semax a controlled substance?
It is not scheduled under the US Controlled Substances Act as of writing and it holds no FDA approval for any indication. Anti-doping status and import rules vary by jurisdiction and by governing body, and analogue clauses can capture compounds not listed by name, so confirm current status directly with the relevant authority before shipping or using it under a sporting or institutional framework.
