Cerebrolysin vs N-Acetyl Selank Amidate
A side-by-side research comparison of Cerebrolysin and N-Acetyl Selank Amidate across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Cerebrolysin | N-Acetyl Selank Amidate |
|---|---|---|
| Full name | Cerebrolysin (Brain-Derived Peptide Preparation) | N-Acetyl Selank Amidate (NA Selank) |
| Category | Cognitive & Nootropic | Cognitive & Nootropic |
| Status | Investigational | Research compound |
| Mechanism | Contains fragments mimicking NGF, BDNF, GDNF, CNTF. Enhances synaptic plasticity, promotes neuronal sprouting, reduces amyloid-beta, and stabilizes calcium homeostasis. | Modulates GABA and serotonin systems and influences BDNF and the expression of enkephalin-degrading enzymes, producing anti-anxiety and mood-stabilizing effects. The acetyl/amidate modifications extend its duration. |
| Molecular weight | <10,000 Da (peptide fraction) | ~800 Da |
| Half-life | 4-6 hours | Longer than base Selank |
| Bioavailability | High (IM/IV) | Intranasal (primary); subcutaneous also used |
| Typical dose | 5-30 mL | ~300-900 mcg per day |
| Frequency | Daily for 10-20 days | 1-2x daily |
| Route | Intramuscular or IV | Intranasal spray/drops |
