What is the difference between Cerebrolysin and Semax?

Cerebrolysin: Standardized mixture of neuropeptides derived from porcine brain proteins; mimics endogenous neurotrophic factors (BDNF, NGF, CNTF); promotes neurogenesis and synaptic plasticity Semax: Semax is believed to upregulate brain-derived neurotrophic factor (BDNF) and other neuroprotective factors, enhancing neuronal survival and synaptic plasticity.

Is Cerebrolysin FDA approved?

Cerebrolysin is investigational and not FDA approved. It is discussed for research and educational purposes only, not as medical guidance.

Is Semax FDA approved?

Semax is the subject of a favorable FDA advisory committee vote but not FDA approved, and its legal status for compounding is unchanged. It is discussed for research and educational purposes only, not as medical guidance.

How is Cerebrolysin administered in research settings?

In research settings, Cerebrolysin is typically administered via the intravenous or intramuscular routes. PeptideBase does not provide dosing or administration instructions.

How is Semax administered in research settings?

In research settings, Semax is typically administered via the intranasal or subcutaneous routes. PeptideBase does not provide dosing or administration instructions.

About Cerebrolysin

Research Areas

About Semax

Semax is believed to upregulate brain-derived neurotrophic factor (BDNF) and other neuroprotective factors, enhancing neuronal survival and synaptic plasticity. It modulates the dopaminergic and serotonergic systems, contributing to its reported effects on mood and focus. Its mechanism of action differs from classical stimulants — it does not act on adrenergic receptors and does not produce typical stimulant tolerance or dependence patterns.

Semax

No established clinical contraindications. This is an investigational compound with limited human data and has not been evaluated by the FDA for safety in this context. Consult a qualified clinician.

Used Together?

Semax

Selank
Research suggests Semax and Selank may produce complementary cognitive and stress-modulating effects when combined. Semax is studied for BDNF upregulation and cognitive enhancement, while Selank is studied for anxiolytic and immune-regulatory activity — distinct mechanisms with potential overlap in neuroprotective signaling.
