Semax is a synthetic ACTH(4-10) analog developed for stroke and cognitive disorders. It upregulates BDNF and NGF, modulates serotonergic and dopaminergic neurotransmission, and has received regulatory approval in Russia for stroke treatment. Research shows improvements in memory, attention, and neuroprotection.

Semax Acetate ACTH (4-10) Analog
  • Neurology: Semax is studied in stroke recovery and ischemic neuroprotection research, with regulatory approval in Russia for acute stroke treatment. Research examines its effects on infarct volume reduction, neurological deficit scores, and functional recovery following ischemic events. Studies investigate the mechanisms of neuroprotection, including BDNF/NGF upregulation, anti-apoptotic signaling, and cerebrovascular blood flow modulation.
  • Cognitive Science: Semax is extensively studied for its nootropic effects on memory formation, attention, and executive function. Research demonstrates enhanced performance on spatial memory tasks, improved working memory capacity, and accelerated cognitive processing speed. Studies examine whether these effects are mediated through neurotrophic factor upregulation, cholinergic system modulation, or dopaminergic pathway enhancement.
  • Neuropharmacology: Semax is a model compound for studying BDNF and NGF upregulation mechanisms. Research examines the time course of neurotrophic factor elevation, the receptor systems involved, and the downstream effects on synaptic plasticity, long-term potentiation, and dendritic morphology. These fundamental studies inform therapeutic development for neurodegenerative and cognitive disorders.
  • Clinical Neuroscience: Semax serves as one of the few regulatory-approved nootropic peptides, providing validated clinical study models for cognitive enhancement research. Russian clinical data spanning decades provides a foundation for studying long-term nootropic efficacy, safety, and the translation of preclinical neurotrophic effects into measurable cognitive outcomes in human subjects.

Storage Conditions

Unreconstituted

Store at -20°C to 4°C (freezer or refrigerator). Stable for 24+ months.

Reconstituted

Refrigerate at 2–8°C. Use within 30 days for optimal stability.

Avoid

Repeated freeze-thaw cycles, direct sunlight, and temperatures above 25°C.

Safety & Compliance

  • Wear nitrile gloves and safety goggles when handling research compounds.
  • Work in a clean, controlled environment (laminar flow hood recommended).
  • Dispose of sharps and used materials in approved biohazard containers.
  • This product is for laboratory research use only (RUO) — not for human or veterinary use.
