Semax 99% purity Synthetic Neuropeptide for Cognitive Function and Neuroprotection Research

• Semax is a synthetic heptapeptide (7 amino acids: Met‑Glu‑His‑Phe‑Pro‑Gly‑Pro) and a modified analog of the ACTH (4‑10) fragment. It is primarily used as a nootropic, neuroprotective, and neurorestorative agent. 
  It can effectively cross the blood‑brain barrier, support the production of BDNF (Brain‑Derived Neurotrophic Factor) and NGF (Nerve Growth Factor), and help regulate key neurotransmitters including dopamine and serotonin.
  Semax is widely studied for its ability to improve cognitive functions such as memory, focus, attention, and learning ability, while also reducing mental fatigue and supporting brain recovery under stress.
  It also exhibits strong neuroprotective effects against cerebral ischemia, traumatic brain injury, and oxidative stress, making it valuable in neurological research and related applications.
• Pharmacological Effects:                                         
• Semax exhibits a wide range of pharmacological activities, mainly including nootropic, neuroprotective, neurotrophic, and anti‑hypoxic effects.
  
  
  It can effectively penetrate the blood‑brain barrier, enhance the synthesis and release of brain‑derived neurotrophic factor (BDNF) and nerve growth factor (NGF), thereby promoting neuronal survival, growth, and repair.
  
  
  Semax improves cognitive functions such as learning, memory, attention, and concentration, and reduces mental fatigue and stress‑related brain dysfunction. It also shows strong neuroprotective effects against cerebral ischemia, hypoxia, traumatic brain injury, and oxidative stress.
  
  
  In addition, Semax can regulate the metabolism of central neurotransmitters (dopamine, serotonin, etc.), exerting mild anxiolytic and mood‑stabilizing effects. It also improves cerebral microcirculation and increases the brain’s resistance to adverse stimuli, making it widely studied in the field of neurological function regulation and recovery.
