How does cortexin work?

Cortexin is a mix of small peptides taken from the brain surface (cortex) of cattle. This site's profile suggests it acts like a brain growth signal and protects nerve cells. How long it lasts varies, because it is a mix. There is no single molecular weight. The one study in people on that page is a Russian study of repeated low-dose Cortexin courses in stroke patients. It was not independently replicated outside that research school. Doctors use it in Russia and nearby countries. It is not FDA approved. A 2021 study in rats and mice found Cortexin protected nerve cells in short-term and long-term models of low blood flow to the brain, compared with Cerebrolysin and Actovegin. Those animal findings do not transfer into a counted Western stroke result. This FAQ does not invent a human mechanism. Full record at /compounds/cortexin.
