What it is
A peptide preparation derived from bovine or porcine cerebral cortex, developed in Russia. Supplied as a lyophilized powder for intramuscular injection.
How it works
Proposed in Russian research literature to exert neurotrophic and neuroprotective effects via a mixture of low-molecular-weight cortex-derived peptides, though mechanisms are not well characterized.
Where it's used
Approved in Russia and several neighboring countries for stroke, encephalopathy, and cognitive impairment. Not approved in the US.
Regulatory status
Not FDA-approved; research compound in the US.
Reconstitution
Supplied as a lyophilized powder reconstituted with sterile water or saline prior to intramuscular injection.
Tracking it
Cortexin is injectable, so two things matter in a log: when you dosed and where. Rotating sites and writing both down prevents the classic “did I already pin the left side?” problem.
