Semax Research Reference
A documentation-focused reference page for Semax as a research compound. It covers what the material is, its research context, how purity and identity are verified, and how it is stored and handled in the lab. No effects are claimed. Supplied for research use only.
What it is
Semax is a synthetic peptide developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It is one of two Russian-developed research peptides (alongside Selank) that have been studied in laboratory neuroscience research. As a research compound it is supplied as a lyophilized powder.
Research context
Semax is referenced in laboratory neuroscience research, where it is studied alongside related synthetic peptides. This page notes only that Semax is a referenced compound in published neuroscience research; it makes no claim about any effect. A purity-verified reference material provides a defined, characterized compound for study in these contexts.
How purity is verified
The material is characterized per lot:
- HPLC for purity, read with the chromatogram; research-grade material is ≥99% by reverse-phase HPLC.
- Mass spectrometry for identity, matching the observed mass to the theoretical mass.
- LAL (Limulus Amebocyte Lysate) for bacterial endotoxin, commonly referenced to USP <85>.
All three results are documented on a lot-matched certificate tied to the lot number on the vial. Material is synthesized in the USA.
Storage and handling for lab use
General laboratory handling notes for lyophilized Semax:
- Lyophilized powder. Store at -20°C. Keep the vial sealed and dry until ready to reconstitute.
- Reconstitution. Bacteriostatic water is the most commonly referenced solvent. Add slowly along the vial wall and swirl gently rather than shaking.
- Reconstituted solution. Commonly refrigerated at 2-8°C and referenced as stable for roughly 30 days at 2-8°C once reconstituted, at a mildly acidic to neutral pH (approximately 5-7). Avoid repeated freeze-thaw cycles.
Exact parameters depend on your protocol and the requirements of the work.

What is Semax?
Semax is a synthetic peptide developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It is supplied as a lyophilized powder for research use and is studied in laboratory neuroscience research alongside related peptides such as Selank.
How is Semax purity verified?
Per lot, using reverse-phase HPLC for purity (≥99% research-grade), mass spectrometry for identity, and the LAL assay for endotoxin, all documented on a lot-matched certificate of analysis.
How should Semax be stored?
As a lyophilized powder at -20°C, kept sealed and dry until reconstitution. Reconstituted solution is commonly refrigerated at 2-8°C and referenced as stable for around 30 days, with freeze-thaw cycles avoided.
What solvent is used to reconstitute Semax?
Bacteriostatic water is the most commonly referenced solvent. Add it slowly along the vial wall and swirl gently; store the reconstituted solution refrigerated at 2-8°C.
Is research Semax for human use?
No. It is supplied for research use only, as a characterized laboratory reference compound, not for human, veterinary, or diagnostic use. ## Related pages - Semax product page and lot COA - How to verify research peptide purity - Browse the research catalog
