Cerebrolysin vs GHRP-6

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.

GHRP-6

Growth Hormone Releasing Peptide 6 (GHRP-6) is one of the first synthetic growth hormone secretagogues discovered. It stimulates significant GH release but is known for causing intense hunger.

Side-by-Side Comparison

Aspect	Cerebrolysin	GHRP-6
Dose Range	2150 mg–4300 mg	100 mcg–300 mcg
Frequency	1x daily	3x 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 GHS-R receptor in the pituitary and hypothalamus. Stimulates GH release and also significantly increases appetite by mimicking ghrelin's hunger-signaling effects.
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 combined with GHRH peptides like CJC-1295 for synergistic effects.
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 administered on an empty stomach. The strong hunger response can be beneficial for those trying to gain weight but challenging for cutting.
Side Effects	Generally well-tolerated. May cause dizziness, headache, sweating, or injection site reactions. Rare cases of agitation or confusion.	Intense hunger (most notable effect), water retention, increased cortisol and prolactin, tingling/numbness, and potential blood pressure changes.
