Why is Semax not classified as a dietary supplement in the United States?

Semax is not considered a dietary supplement in the United States because it is a synthetic peptide, not a natural compound found in food, and therefore does not meet the legal definition. It has not undergone the FDA approval process required for either supplements or pharmaceuticals in the U.S.

What is the regulatory status of Semax in the United States and the European Union?

In the United States, Semax is not FDA-approved for human use and is often sold as an unscheduled 'research chemical' or 'peptide for research purposes only.' Similarly, it is not approved by the EMA in the European Union, with its status varying by country but generally available through research peptide suppliers.

How can researchers verify the authenticity and purity of Semax purchased for study?

Researchers should demand a Certificate of Analysis (CoA) demonstrating ≥98% purity and insist on independent third-party testing, such as HPLC and Mass Spectrometry, to confirm identity. Key checks include verifying the correct molecular weight (813.92 g/mol) and amino acid sequence (Met-Glu-His-Phe-Pro-Gly-Pro).

What are the primary clinical applications for Semax in Russia, where it is an approved pharmaceutical?

In Russia, Semax is an approved prescription pharmaceutical with established clinical uses for conditions such as stroke recovery, cognitive impairment, and peptic ulcers. It is administered as a nasal spray within the Russian healthcare system.

Is extensive Western clinical data available for Semax?

While Semax has a significant body of research and clinical application originating from Russia, extensive Western clinical trial data is limited. Researchers should be aware that the majority of published studies and clinical experience primarily come from Russian scientific literature.
