Check formulation: Lyophilized powder requires reconstitution before use. Pre-mixed solutions are more convenient but may have a shorter shelf life and higher prices.
Compare per-mg cost: Different strengths and quantities make direct price comparison difficult. Calculate the per-milligram cost to find the true best value.
Verify COAs: Look for vendors that publish per-batch Certificates of Analysis from named, accredited labs. Every vendor on this page is verified for endotoxin testing — not just HPLC purity.
Semax's evidence base is primarily Russian-language clinical literature. Gusev, Skvortsova and colleagues reported improved neurological recovery in acute hemispheric ischemic stroke when Semax was added to conventional therapy (Zh Nevrol Psikhiatr, 1997; PMID 11517472), and subsequent Russian studies extended use to cerebrovascular insufficiency (PMID 15792140). Preclinical work by Dolotov, Myasoedov and colleagues demonstrated that intranasal Semax rapidly elevates BDNF protein and TrkB activation in rat hippocampus and basal forebrain (Brain Res 2006, PMID 16996037; J Neurochem 2006, PMID 16635254). Genome-wide transcriptional analysis by Medvedeva et al. in rat focal ischemia showed Semax modulates a broad panel of immune-response and vascular-system genes (BMC Genomics 2014, PMID 24661604). Western evidence is limited; Semax has not been evaluated by the FDA and has no pivotal trials in the US or EU.
