What is Semax?
Semax is registered in the Russian Federation as a prescription pharmaceutical, and was developed at the Russian Academy of Sciences' Institute of Molecular Genetics. In the UK it has no marketing authorisation; Diluent supplies it as a research compound.
Published work includes measurement of BDNF protein in the rat basal forebrain (PMID 14556513); region-by-region gene expression of BDNF and NGF in the brain (PMID 19662538); and a stroke rehabilitation study of 110 patients, neither randomised nor placebo-controlled, in Zhurnal Nevrologii i Psikhiatrii, 2018.
How are these supplied?
The nasal spray comes in solution; the 5mg Semax vial is freeze-dried and must be made up.
Questions on Cognitive & Sleep
Where is Semax approved?
In Russia, where it carries a pharmaceutical registration. The UK and the EU have none, and ours is sold as a research compound.
How does the Semax vial differ from the nasal spray?
Just the state. The 5mg vial holds powder to be made up; the spray comes ready mixed.
