Semax

Description

Semax is a synthetic heptapeptide derived from a fragment of adrenocorticotropic hormone (ACTH 4-10), developed in Russia and studied for decades in nootropic and neuroprotective research. Unlike ACTH itself, Semax has no hormonal activity on the adrenal axis — the modification strips that effect out while preserving central nervous system activity, which is the whole point of the fragment.

Research on Semax focuses on brain-derived neurotrophic factor (BDNF) expression and cognitive-performance models, making it a frequently cited reference compound in nootropic peptide research alongside Selank, with which it shares a similar Russian pharmacological research lineage.

For laboratory research use only. Semax is typically studied via intranasal or in-vitro protocols; store the lyophilised or solution form refrigerated and protected from light.
