Side-by-side comparison
| Cortexin | Memantine | |
|---|---|---|
| Category | Sleep & Recovery | Cognitive Enhancement |
| Regulatory status (US) | Research use only | Research use only |
| Typical dosage | 10 mg | 5-20 mg |
| Frequency | evening | daily |

| Reported side effects | Generally well-tolerated | Dizziness, headache possible |
Key differences
Primary use. Cortexin is categorised under Sleep & Recovery, while Memantine falls under Cognitive Enhancement. Their differing categories mean they are usually chosen for different goals rather than as direct substitutes.
Regulatory status. Cortexin: not FDA-approved; treated as a research compound. Memantine: not FDA-approved; treated as a research compound.
Dosing. Cortexin is typically dosed at 10 mg (evening). Memantine is typically dosed at 5-20 mg (daily).
Can you stack them?
Some protocols combine peptides, but stacking Cortexin and Memantine 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.
