Semax is a synthetic heptapeptide developed at the Institute of Molecular Genetics, Russian Academy of Sciences in the 1980s as a neuroprotective agent for stroke and brain trauma. It mimics the N-terminal fragment of adrenocorticotropic hormone (ACTH 4-10) but lacks hormonal activity, instead promoting BDNF synthesis, modulating serotonin/dopamine systems, and enhancing gene expression for vascular/immune repair. Approved in Russia for acute ischemic stroke and cognitive disorders, it remains a leading research tool for nootropic and neuroprotective studies. This research-grade lyophilized powder is synthesized under strict quality controls and provided with full analytical documentation.

Key Scientific

  • High-purity Semax (≥ 98% by HPLC/MS, acetate salt form)
  • Verified heptapeptide sequence: Met-Glu-His-Phe-Pro-Gly-Pro (MEHFPGP)
  • Lyophilized formulation for maximum long-term stability
  • Full Certificate of Analysis (COA) with HPLC, MS, and amino acid analysis
  • Manufactured in GMP-aligned, ISO-compliant facilities
  • Ideal for BDNF modulation, ischemia models, and cognitive performance research

Research-Referenced Attributes (Based on scientific literature; not intended as therapeutic claims.)

  • Increases BDNF expression and hippocampal neurogenesis for cognitive enhancement and memory consolidation
  • Neuroprotective in focal ischemia models: reduces infarct size by 20-30% via vascular/immune gene upregulation
  • Improves stroke recovery: enhances motor function and reduces neurological deficits in clinical trials (n=110)
  • Antioxidant effects at low doses; modulates enkephalinase inhibition for stress resilience
  • Enhances learning in avoidance tasks and reduces heavy metal toxicity in animal models
  • Nasal bioavailability >80%; crosses blood-brain barrier effectively

Why Researchers Choose Nationwide Peptides Semax

  • Exact Russian clinical-sequence match for authentic neuroprotective effects
  • Highest documented BDNF induction among research suppliers
  • Transparent analytical data (HPLC >98%, MS confirmation)
  • Trusted by neurology, cognitive science, and pharmacology laboratories
  • Competitive research pricing with bulk options

Storage & Handling

  • Store lyophilized powder at –4 °F (long-term) or 39.2 °F (short-term)
  • Store in a tightly sealed container and protect from light, moisture, air exposure, and elevated temperatures.
  • Reconstitute only with sterile water or saline for nasal spray (typical concentration 0.1-1% solution)
  • Reconstituted solutions stable at 39.2 °F for up to 2 weeks; avoid repeated freeze-thaw cycles
  • Use appropriate PPE and aseptic technique
