How it works

Semax is a synthetic heptapeptide derived from a fragment of ACTH (4-10). Research focuses on how it modulates neuropeptide and neurotrophic signaling, including BDNF activity, in studies of cognition, focus, and neuroprotection.

Azoth supplies Semax strictly as a research-use-only material, synthesized in the U.S. for in vitro and preclinical research and backed by third-party verified, >99% purity, so your data rests on consistent, well-characterized material.

Testing & COA

Every Azoth batch is analyzed by an independent US laboratory using HPLC, mass spectrometry, and endotoxin testing. The certificate of analysis for the current batch is linked above and archived in our lab results library.

Common Questions.

View lab results →
How pure are Azoth peptides, and what is your testing protocol?

Every batch is analyzed by an independent US laboratory via HPLC, mass spectrometry, and endotoxin testing, with >99% verified purity. The certificate of analysis for your batch is linked on each product page.

How do I interpret a Certificate of Analysis (COA)?

Each COA lists the compound identity, batch number, HPLC purity percentage, and the testing laboratory. Match the batch number on your vial to the COA in our lab results library.

What reconstitution solvent is recommended?

Bacteriostatic water is the standard solvent for laboratory reconstitution of lyophilized peptides. Follow your protocol’s guidance for concentration.

What are the optimal storage conditions for lyophilized compounds?

Store sealed vials refrigerated and protected from light. Reconstituted material should be used promptly according to your research protocol.

Do the nasal spray formats need to be refrigerated?

No. The nasal sprays do not need to be refrigerated, but we recommend refrigeration to extend their integrity. Keep them out of heat and direct light, and returning them to cold storage between uses helps preserve the compound.
