What is the difference between Cerebrolysin and Selank?

Cerebrolysin (Cerebrolysin (porcine brain peptide complex)) is graded B and is Not FDA-approved in US — approved in 50+ countries for stroke, traumatic brain injury, and dementia. Selank (Selank (TP-7)) is graded B and is Not FDA-approved in US — approved in Russia as anxiolytic. They are commonly compared because they share the categories: cognitive.

Which has stronger clinical evidence — Cerebrolysin or Selank?

On our internal evidence scale, Cerebrolysin is B and Selank is B. A+ indicates large RCTs plus FDA approval; C indicates primarily preclinical or anecdotal evidence.

What is the typical dose of Cerebrolysin vs Selank?

Cerebrolysin: Trial range: 5–30 mL daily (intravenous infusion). Selank: 200–400 mcg intranasal, evening. Always work with a licensed clinician — peptide dosing should be individualized.

Cerebrolysin vs Selank

Both Cerebrolysin and Selank are used for cognitive. Here's how their evidence, dosing, and regulatory status actually compare.

Cerebrolysin

Evidence B

Cerebrolysin (porcine brain peptide complex)

A standardized mixture of low-molecular-weight peptides from porcine brain. Decades of stroke, dementia, and TBI trial data — modest but consistent cognitive recovery effects.

Selank

Evidence B

Selank (TP-7)

A synthetic analog of tuftsin with anxiolytic and nootropic properties. Modulates GABA and serotonin systems to reduce anxiety without sedation.
