ACTH(4-10)-derived heptapeptide — studied for raising BDNF and attention.
Purity ≥98.7% HPLCFormat Lyophilized powderSKU SEMResearch use only
Overview
Semax is a synthetic heptapeptide derived from a fragment of adrenocorticotropic hormone (ACTH(4-10)), stabilized against enzymatic breakdown. It is studied in neuroactive research for its reported effects on BDNF and NGF expression, neuroprotection and cognitive/attention pathways.
It is commonly investigated via intranasal delivery in research settings due to its peptide nature. Supplied as research-grade material for laboratory use only.
Research applications
- BDNF / NGF expression and neurotrophic signaling
- Cognition, attention and memory research models
- Neuroprotection and ischemia research
- Stress-adaptation and neuromodulation studies
- Dopaminergic and serotonergic pathway research
- Comparison with related nootropic peptides (Selank, etc.)

Open the calculator →Handling & storage
Supplied as a lyophilized powder. Store at 2–8 °C on receipt; protect from heat, light and moisture, and avoid excessive agitation. If reconstitution is required for laboratory work, use sterile technique — bacteriostatic water, or 0.6% acetic acid for low-solubility peptides. Protocols vary by research application.
