Lowest $/mg for Semax · verified listings only
$2.17/mg
▼ 6% over 90d
Alpha Peptides has the lowest single-vial Semax price at $2.08/mg among 36 COA-verified vendors on Disclosed Labs. Bulk or multi-vial deals may be lower. That's 70% less per mg than the most expensive option.
What is the price range for Semax?
Research-grade Semax ranges from $2.08/mg to $7.00/mg across 23 verified sources, a 70% spread per mg.
How are Semax prices verified on Disclosed Labs?
Every listed vendor holds a Grade C or better trust score, computed independently from lab Certificates of Analysis — not from payments or sponsorships. Prices are scraped and fact-checked daily. Vendors cannot pay to improve their ranking.
Semax is on the FDA Pharmacy Compounding Advisory Committee (PCAC) July 23–24, 2026 meeting docket for consideration for the Category 1 (503A) authorized compounding list. The PCAC is advisory only — it reviews nominations and makes recommendations; the FDA issues any final rule later. No decision has been made. If eventually added to the Category 1 list, a valid prescription would be required.
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. Use the Full safety panel filter to require endotoxin, sterility, and heavy-metals testing on the current batch — 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.
