Cerebrolysin

Cognitive & Neurological

Semax and Cerebrolysin are both neuroprotective peptides with clinical use, but they differ significantly in composition, administration, and primary applications. Semax is a single defined peptide, while Cerebrolysin is a complex mixture of brain-derived factors. Understanding these differences is crucial for cognitive enhancement strategies.

Key Similarities

  • Both have neuroprotective properties
  • Both are approved for clinical use (not US)
  • Both may help stroke recovery
  • Both support cognitive function
  • Both work through neurotrophic mechanisms
  • Both have good safety profiles

Key Differences

  • Semax is a single peptide; Cerebrolysin is a mixture
  • Semax is intranasal; Cerebrolysin requires injection
  • Cerebrolysin has more extensive clinical use
  • Semax is easier for self-administration
  • Cerebrolysin typically for more severe conditions
  • Semax more often used for enhancement; Cerebrolysin for treatment

When to Choose Each

Choose Semax

Choose Semax for cognitive enhancement, mood support, or mild neuroprotection with convenient intranasal dosing. Ideal for daily nootropic use or as an accessible neuroprotective agent.

Choose Cerebrolysin

Choose Cerebrolysin for more significant neurological concerns—stroke recovery, TBI, or dementia. Its complex mixture of neurotrophic factors is suited for therapeutic applications under medical supervision.

Can You Stack Them?

Some combine Semax for daily nootropic use with periodic Cerebrolysin courses for intensive neurological support. They work through overlapping but distinct mechanisms, so combination may be synergistic.

Frequently Asked Questions

Semax is more practical for daily nootropic use due to easy intranasal administration. Cerebrolysin is better suited for therapeutic intervention than daily enhancement.
Cerebrolysin requires IM or IV injection, typically administered in clinical settings. While some self-administer IM, it's less convenient than Semax's intranasal route.
Cerebrolysin has more extensive clinical use (50+ years, 40+ countries). Semax has strong research but primarily from Russia with growing international interest.
