Cortexin

Cortexin (bovine/porcine cerebral cortex polypeptide complex)

Research useEducational entry
Mechanism

A low-molecular-weight polypeptide mixture extracted from the cerebral cortex of cattle or pigs, studied for neurotrophic and neuroprotective signalling; because it is a complex mixture rather than a single molecule, any proposed activity reflects the sum of many peptide interactions.

Evidence

Registered and marketed as a neurological medicine in Russia and some post-Soviet states; the clinical and preclinical evidence base is mostly Russian, often open-label, with limited independent replication. Not approved by the FDA or EMA.

Applications
  • Studied in brain ischemia and stroke recovery
  • Researched for cognitive dysfunction in children
  • Explored in various CNS and post-viral neurological conditions
Protocol

Educational overview only — no dosing instructions in the public hub.

Risks

Animal-derived biological product; long-term and independent human safety data are limited, and sourcing/purity plus the absence of Western regulatory oversight are the main practical risks.

Quality

Third-party CoA (identity, purity + quantification) plus documented animal-tissue origin controls are the minimum verification for a biological extract.

Legal status

Registered as a prescription drug in Russia and several post-Soviet countries; not approved for human use in the EU, UK, or US, where it is treated as research-use-only or unapproved.
