Brief Description

Heptapeptide derived from ACTH(4-10) — the active fragment of adrenocorticotropic hormone — with a stabilizing extension for metabolic resistance. Unlike full-length ACTH, Semax does not stimulate adrenal steroidogenesis, isolating its neurotropic activity. It upregulates BDNF and NGF expression and modulates dopaminergic and serotonergic systems. Research areas include neuroprotection after ischemic injury, cognitive function, neurotrophic factor regulation, and cerebrovascular function. For research use only — not for human consumption.
