Sermorelin & GHRP-2 & GHRP-6 vs Cerebrolysin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Sermorelin & GHRP-2 & GHRP-6
A powerful tri-blend combining Sermorelin (a GHRH analog) with two growth hormone releasing peptides. This combination produces significantly greater GH release than any single peptide, with studies showing up to 54-fold increases in pulsatile GH secretion.

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.

| Aspect | Sermorelin & GHRP-2 & GHRP-6 | Cerebrolysin |
|---|---|---|
| Mechanism | Sermorelin stimulates the pituitary via GHRH receptors, while GHRP-2 and GHRP-6 act as ghrelin mimetics on different receptor subtypes. The combination creates synergistic GH release through multiple complementary pathways. GHRP-6 also strongly stimulates appetite. | Contains multiple neurotrophic factors that promote neuroplasticity, reduce neuronal apoptosis, and support synaptic function. Has both neurotrophic and neuroprotective properties. |
| Typical Dosage | Typical protocols: Sermorelin 100-300mcg, GHRP-2 100-300mcg, GHRP-6 100-300mcg. Often administered 2-3 times daily, 30 minutes before meals or at bedtime. | 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 | Subcutaneous injection. Best administered fasted or before sleep to maximize natural GH cycle. The three peptides can be mixed together or administered separately. | Administered via intramuscular or intravenous injection. IV administration is typically used in clinical settings. IM can be used for research purposes. |
| Side Effects | Increased hunger (especially from GHRP-6), water retention, facial flushing, nausea, tingling, potential increases in cortisol and prolactin levels. | Generally well-tolerated. May cause dizziness, headache, sweating, or injection site reactions. Rare cases of agitation or confusion. |
