Cerebrolysin vs Thymalin

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.

Side-by-Side Comparison

AspectCerebrolysinThymalin
MechanismContains multiple neurotrophic factors that promote neuroplasticity, reduce neuronal apoptosis, and support synaptic function. Has both neurotrophic and neuroprotective properties.Regulates the ratio of T-cell subpopulations, stimulates cellular immunity, and enhances phagocytosis. Also affects neuroendocrine regulation and may influence melatonin production.
Typical DosageClinical dosing: 10-30ml IV daily for acute conditions. Research use: 5-10ml IM daily for cognitive enhancement. Treatment courses typically last 10-20 days.Clinical protocols: 5-20mg daily intramuscularly for 3-10 days. Often cycled 1-2 times per year for maintenance.
AdministrationAdministered via intramuscular or intravenous injection. IV administration is typically used in clinical settings. IM can be used for research purposes.Intramuscular injection. Usually administered in short courses rather than continuously. Often combined with Epithalamin for anti-aging protocols.
Side EffectsGenerally well-tolerated. May cause dizziness, headache, sweating, or injection site reactions. Rare cases of agitation or confusion.Generally well-tolerated. May cause injection site reactions or temporary flu-like symptoms as immune function is modulated.
