About Cortexin

What it is

Cortexin is a mixture of low-molecular-weight polypeptides extracted from the cerebral cortex of cattle, developed and marketed in Russia as a neuroprotective drug. It is approved and used in Russia and some neighboring countries but has no FDA approval and is considered investigational in the United States. Published research covers ischemic brain injury and cognitive and developmental disorders, mostly in small Russian studies.

How it works

It is thought to promote neuron survival and modulate glutamate and GABA signaling, though the mechanism is not fully defined.

Disclosure. Some vendors above are Peptul partners and pay us a commission when you buy through our link. Rows are ordered by: Peptul partners first, then what is in stock, then single vials before multi-vial packs, then price per milligram. Paying us moves a vendor up this order and changes nothing else - not their trust tier, COA badge, Peptul Score or reviews, which come from evidence and are worked out the same way for everyone. Available discount codes are shown beside the prices above. Discounted prices require the displayed code where indicated.
