Cerebrolysin vs Cortexin
Overview
Cerebrolysin is primarily a pain management peptide, while Cortexin is used for sleep & recovery.
This page compares Cerebrolysin and Cortexin across their primary use, typical dosing, reported benefits and side effects, and U.S. regulatory status. For the full monograph on either compound — mechanism of action, clinical research, and references — follow the article links.
Side-by-side comparison
| Cerebrolysin | Cortexin | |
|---|---|---|
| Category | Pain Management | Sleep & Recovery |
| Regulatory status (US) | Research use only | Research use only |
| Typical dosage | 5-10 ml | 10 mg |
| Frequency | multiple weekly | evening |
| Reported benefits | Nerve pain reduction, neuroprotection, stroke pain support | Enhanced sleep quality, neural recovery, stress reduction |
| Reported side effects | Generally well-tolerated | Generally well-tolerated |
Key differences
Primary use. Cerebrolysin is categorised under Pain Management, while Cortexin falls under Sleep & Recovery. Their differing categories mean they are usually chosen for different goals rather than as direct substitutes.
Regulatory status. Cerebrolysin: not FDA-approved; treated as a research compound. Cortexin: not FDA-approved; treated as a research compound.
Dosing. Cerebrolysin is typically dosed at 5-10 ml (multiple weekly). Cortexin is typically dosed at 10 mg (evening).
Can you stack them?
Some protocols combine peptides, but stacking Cerebrolysin and Cortexin has not been validated for safety or efficacy in controlled trials. Combining compounds can change their effects and risks. Nothing here is medical advice — consult a qualified healthcare provider before starting or combining any protocol.
