Cerebrolysin vs Ipamorelin
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 →Ipamorelin
Ipamorelin is a selective growth hormone secretagogue that stimulates the release of growth hormone from the pituitary gland without significantly affecting cortisol or prolactin.
Full details →Side-by-Side Comparison
| Aspect | Cerebrolysin | Ipamorelin |
|---|---|---|
| Dose Range | 2150 mg–4300 mg | 100 mcg–300 mcg |
| Frequency | 1x daily | 2x daily |
| Cycle Length | 1–2 weeks | 8–12 weeks |
| Route | intramuscular | subcutaneous |
| Mechanism | Contains multiple neurotrophic factors that promote neuroplasticity, reduce neuronal apoptosis, and support synaptic function. Has both neurotrophic and neuroprotective properties. | Acts as a ghrelin mimetic, binding to the ghrelin receptor (GHS-R) in the pituitary to stimulate GH release. Highly selective with minimal effect on other hormones. |
| 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 ranges from 200-300mcg administered 2-3 times daily, often combined with CJC-1295. |
| Administration | Administered via intramuscular or intravenous injection. IV administration is typically used in clinical settings. IM can be used for research purposes. | Subcutaneous injection. Best results when administered fasted or before sleep. Often stacked with GHRH peptides. |
| Side Effects | Generally well-tolerated. May cause dizziness, headache, sweating, or injection site reactions. Rare cases of agitation or confusion. | Generally well-tolerated. May cause mild headaches, lightheadedness, or increased hunger initially. |
