Description
Semax is a synthetic heptapeptide analogue of the ACTH (4-10) fragment with nootropic, neuroprotective, and anxiolytic properties. It modulates the expression of neurotrophins and supports neuronal survival under stress conditions such as hypoxia and glutamate toxicity. Semax is studied for its potential to improve cognitive functions, neuroplasticity, and brain circulation in various research models.
