| Aspect | Selank | Cerebrolysin |
|---|---|---|
| Mechanism | Modulates the expression of brain-derived neurotrophic factor (BDNF) and affects serotonin and norepinephrine systems. Has immunomodulatory and anxiolytic properties. | Contains multiple neurotrophic factors that promote neuroplasticity, reduce neuronal apoptosis, and support synaptic function. Has both neurotrophic and neuroprotective properties. |
| Typical Dosage | Intranasal administration: 250-500mcg 2-3 times daily. Subcutaneous: 250-500mcg daily. | Clinical dosing: 10-30ml IV daily for acute conditions. Research use: 5-10ml IM daily for cognitive enhancement. Treatment courses typically last 10-20 days. |
| Administration | Most commonly administered intranasally for cognitive effects. Can also be injected subcutaneously. | Administered via intramuscular or intravenous injection. IV administration is typically used in clinical settings. IM can be used for research purposes. |
| Side Effects | Generally well-tolerated. Some users report mild fatigue or nasal irritation with intranasal use. | Generally well-tolerated. May cause dizziness, headache, sweating, or injection site reactions. Rare cases of agitation or confusion. |
