Cerebrolysin vs TB-500

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

Aspect	Cerebrolysin	TB-500
Dose Range	2150 mg–4300 mg	2 mg–2.5 mg
Frequency	1x daily	Less than daily
Cycle Length	1–2 weeks	4–8 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.	TB-500 promotes cell migration and differentiation, regulates actin (a cell-building protein), and reduces inflammation. It supports the formation of new blood vessels and wound healing.
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.	Research protocols typically use 2-2.5mg twice weekly during the loading phase, followed by maintenance dosing of 2mg every 2 weeks.
Administration	Administered via intramuscular or intravenous injection. IV administration is typically used in clinical settings. IM can be used for research purposes.	Administered via subcutaneous or intramuscular injection. Some protocols suggest injection near injury sites.
Side Effects	Generally well-tolerated. May cause dizziness, headache, sweating, or injection site reactions. Rare cases of agitation or confusion.	May cause temporary fatigue, headache, or localized irritation at injection sites.
