Key Features & Benefits

• Cognitive Enhancement: It is studied for its ability to improve memory retention, attention, and learning capacity.

   

   

• Neuroprotection: Semax helps protect neurons from oxidative stress and may aid in the recovery of damaged neurological functions.

   

   

• Neurotrophic Support: It rapidly elevates levels of Brain-Derived Neurotrophic Factor (BDNF), a protein essential for the growth and survival of new neurons and synapses.

   

   

• Mood & Focus Regulation: By modulating dopamine and serotonin systems, it may help alleviate symptoms of ADHD, anxiety, and depression.

   

   

• Anti-Inflammatory Effects: Research suggests it can reduce the production of pro-inflammatory cytokines in the brain.

   

   

Technical Specifications

• Chemical Structure: A synthetic analogue of the ACTH(4-10) fragment with the sequence Met-Glu-His-Phe-Pro-Gly-Pro.

   

   

• Molecular Formula: C37​H51​N9​O10​S.

• Purity Standards: High-quality research variants typically maintain a purity of ≥ 99% as verified by HPLC.

   

   

• Stability: It is usually provided as a lyophilized (freeze-dried) powder and should be refrigerated after reconstitution to maintain its chemical integrity.

   

   

Available Configurations

Semax is available in several forms, though its biological availability is low when taken orally.

• Nasal Spray: The most common clinical administration method, allowing the peptide to cross the blood-brain barrier effectively.

   

   

• Lyophilized Vials: Typically found in 5mg or 10mg sizes for research use, requiring reconstitution with bacteriostatic water.

   

   

• Modified Variants:

  • N-Acetyl Semax: An acetylated version designed for increased stability and faster crossing of the blood-brain barrier.

  • N-Acetyl Semax Amidate: A further modified version intended for even greater potency and a longer half-life.
