Cortexin
Cortexin is a polypeptide complex derived from pig brain cortex, used clinically in Russia and Eastern Europe for neurological conditions including stroke recovery, traumatic brain injury, and cognitive decline.
Mechanism of Action
Contains a mixture of neuropeptides and amino acids that support neuronal metabolism, provide neuroprotection, and enhance synaptic transmission. Specific mechanisms not fully characterized.
Dosage Overview
Dose Range
10 mg – 20 mg
Route
intramuscular
Frequency
1x daily
Cycle Length
1–2 weeks
Reconstitution
Typical Dosage (Research)
Clinical protocols: 10mg intramuscularly once daily for 10-20 days. May be repeated after 3-6 month interval.
Intramuscular injection. Comes as lyophilized powder requiring reconstitution. Treatment given in courses rather than continuously.
Considerations for Men & Women
Women: Bovine cortex-derived peptide used for cognitive support. Approved in Russia for various neurological conditions. No sex-specific dosing differences. Standard pregnancy precautions.
Men: Same indications and dosing. Intramuscular administration. Short cycling protocols (10 days) apply equally.
Individual responses vary. These notes reflect general trends from research literature and are not medical advice.

Side Effects & Risks
Generally well-tolerated. May cause injection site reactions or mild allergic responses in sensitive individuals.
Derived from animal tissue - theoretical risk of prion contamination. Most research from Russian literature. Not approved in Western countries.
Who Uses Cortexin
Those recovering from neurological injury, individuals seeking cognitive support, patients in Eastern European clinical settings.
