Cerebrolysin vs Noopept
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Cerebrolysin
Cerebrolysin is a mixture of low-molecular-weight neuropeptides and free amino acids derived from purified pig brain proteins. It is approved in many countries for stroke, traumatic brain injury, and dementia.

Noopept (N-phenylacetyl-L-prolylglycine ethyl ester) is a peptide-derived nootropic developed in Russia. While technically a dipeptide prodrug rather than a true peptide, it's often discussed alongside peptide nootropics.
Full details →Side-by-Side Comparison
| Aspect | Cerebrolysin | Noopept |
|---|---|---|
| Mechanism | Contains multiple neurotrophic factors that promote neuroplasticity, reduce neuronal apoptosis, and support synaptic function. Has both neurotrophic and neuroprotective properties. | Metabolized to cycloprolylglycine which modulates AMPA and NMDA receptors, increases NGF and BDNF expression, and provides neuroprotective effects through antioxidant mechanisms. |
| Typical Dosage | 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. | Oral: 10-30mg daily, typically divided into 2-3 doses. Sublingual use may enhance absorption. Some users go higher but effects may plateau. |
| Administration | Administered via intramuscular or intravenous injection. IV administration is typically used in clinical settings. IM can be used for research purposes. | Oral or sublingual administration. Unlike most peptides, it's orally bioavailable. Can be taken with or without food. |
| Side Effects | Generally well-tolerated. May cause dizziness, headache, sweating, or injection site reactions. Rare cases of agitation or confusion. | Headache (often from choline depletion), irritability, insomnia if taken late, and occasional brain fog during initial use. |
