Cerebrolysin vs GHRP-2
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.
Full details →GHRP-2
Growth Hormone Releasing Peptide 2 (GHRP-2) is considered one of the most potent GHRPs available. It provides strong GH release with moderate hunger increase compared to GHRP-6.
Full details →Side-by-Side Comparison
| Aspect | Cerebrolysin | GHRP-2 |
|---|---|---|
| Mechanism | Contains multiple neurotrophic factors that promote neuroplasticity, reduce neuronal apoptosis, and support synaptic function. Has both neurotrophic and neuroprotective properties. | Binds to the ghrelin receptor (GHS-R) to stimulate GH release from the pituitary. Also has some direct effects on the hypothalamus. Causes less appetite increase than GHRP-6. |
| 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. | Typical dosing: 100-300mcg administered 2-3 times daily. Often stacked with GHRH peptides for enhanced GH release. |
| Administration | Administered via intramuscular or intravenous injection. IV administration is typically used in clinical settings. IM can be used for research purposes. | Subcutaneous injection on an empty stomach. Can be used at bedtime to enhance natural GH pulse during sleep. |
| Side Effects | Generally well-tolerated. May cause dizziness, headache, sweating, or injection site reactions. Rare cases of agitation or confusion. | Moderate hunger increase, water retention, potential prolactin and cortisol elevation (less than GHRP-6), tingling sensations. |
