Cortexin polypeptide complex

Cortexin is a polypeptide complex derived from the cerebral cortex of calves or pigs, containing a mixture of neuropeptides and neurotrophic factors. Approved in Russia for stroke, TBI, epilepsy, and cognitive disorders, it exhibits neuroprotective, nootropic, and anticonvulsant properties. Research supports improvements in cognitive function, reduced neurological deficit after stroke, and accelerated recovery from brain injury. It is conceptually similar to Cerebrolysin but derived from cortical tissue.

N-phenylacetyl-L-prolylglycine ethyl ester · GVS-111

Noopept is a dipeptide-derived nootropic approved in Russia for cognitive disorders and memory impairment. It is hydrolyzed in vivo to release cycloprolylglycine, an endogenous neuropeptide. Research demonstrates neuroprotective, memory-enhancing, and anxiolytic effects, upregulation of BDNF and NGF in the hippocampus and cortex, and potential benefits in Alzheimer's disease models. It is significantly more potent than piracetam on a weight-for-weight basis.
