Cognitive comparison

Cerebrolysin vs Semax

An educational, source-based comparison of Cerebrolysin and Semax — how each peptide works, what it's researched for, and what to know before going deeper.

Neurotrophic · Mixture
Cerebrolysin

Porcine-derived peptide mixture researched in neurologic recovery.

Mechanism

A mixture of low-molecular-weight peptides and amino acids derived from purified porcine brain tissue. Research suggests neurotrophic-like activity mimicking BDNF, NGF, and GDNF signaling.

Research areas
  • Ischemic stroke recovery
  • Traumatic brain injury
  • Vascular dementia and Alzheimer's adjunct
Considerations
  • Approved in many countries; not FDA-approved in the US.
  • Mixture composition is not fully characterized.

Nootropic · Neuroprotection
Semax

Russian-origin peptide studied for focus and neuroprotection.

Mechanism

A synthetic heptapeptide derived from ACTH(4-10). Research suggests it modulates BDNF and NGF expression, dopaminergic and serotonergic tone, and shows neuroprotective effects in ischemia models.

Research areas
  • BDNF/NGF upregulation
  • Ischemic stroke recovery (clinical use in Russia)
  • Attention and cognitive performance
  • Anxiolytic-style effects
Considerations
  • Approved as a medication in Russia; not FDA-approved in the US.
  • Most clinical literature is in Russian.
