Cortexin Research Guide

Full name: Cortexin (Polypeptide Brain Extract)

A mixture of low-molecular-weight neuropeptides derived from cattle/pig cerebral cortex, used in some countries for neuroprotection, recovery after stroke or brain injury, and cognitive support.

How Cortexin Works

Provides a blend of neuropeptides and neurotrophic factors thought to support neuronal metabolism, reduce oxidative stress, balance excitatory/inhibitory neurotransmission, and promote neuroprotection and repair.

Dosing Protocol

• Typical dose: ~10 mg per day (course-based)
• Frequency: Once daily
• Duration: 10-day courses, repeatable
• Route: Intramuscular injection

Reported Benefits

• Neuroprotection
• Cognitive and memory support
• Used in stroke/TBI recovery (regional clinical use)
• Antioxidant effects

Potential Side Effects

• Injection site reactions
• Allergic reaction (animal-derived)
• Limited Western clinical data
