Research Comparison

Cerebrolysin vs Semax

A side-by-side research comparison of Cerebrolysin and Semax drawn from Cedar Peptides' peptide database records.

Cerebrolysin

Cerebrolysin is a standardized neuropeptide preparation derived from purified porcine brain proteins, containing a mixture of low-molecular-weight peptides and amino acids with neurotrophic and neuroprotective activity. It is widely studied for neurological recovery, including stroke, traumatic brain injury (TBI), and cognitive decline. The formulation is designed to mimic endogenous neurotrophic factors, supporting neuronal survival, plasticity, and repair. It has been used clinically in multiple countries, with a substantial body of research evaluating its efficacy in neurodegenerative and acute neurological conditions, though outcomes across studies remain mixed.

Semax

Semax is a synthetic heptapeptide derived from adrenocorticotropic hormone (ACTH) fragment 4-10, extensively studied for its nootropic, neuroprotective, and neurorestorative properties. Originally developed in Russia for stroke recovery and approved there as a pharmaceutical, this brain-targeted peptide rapidly increases BDNF levels and modulates dopaminergic and serotonergic systems to enhance cognitive function, memory, and focus. Administered intranasally, Semax is transported directly to the CNS through the olfactory epithelium and trigeminal nerves, bypassing the blood-brain barrier for rapid and efficient brain delivery. Clinical and imaging studies demonstrate enhanced neural connectivity and increased BDNF expression associated with improved cognitive performance and recovery outcomes.

Reading a comparison

A comparison places two records side by side; it does not merge them. Each description above is drawn from that compound's own record, and the two were not necessarily characterised by the same methods, at the same time, or to the same level of detail. Before comparing any attribute, it is worth establishing that both records describe the substance you think they describe — names are not identifiers, and two entries sharing a name can differ in salt form, stereochemistry or the convention used to state a mass. Where a figure carries no method beside it, the comparison is between two reported numbers rather than between two measurements.
