Cerebrolysin vs Semax
Both are nootropic peptide compounds. Here's how they line up on the evidence — graded the same way.
| Cerebrolysin | Semax | |
|---|---|---|
| Evidence | 6/10 | 6/10 |
| Class | Nootropic peptide | Nootropic peptide |
| Summary | Cerebrolysin has more human trial data than most research peptides, yet its largest rigorous stroke trial was neutral and independent reviews find little benefit. | A Russian-approved nootropic/neuroprotective peptide whose human evidence is real but small, mostly Russian-language, and methodologically thin. |

Cerebrolysin
Cerebrolysin is one of the few compounds in the "nootropic peptide" (brain-boosting peptide) world that has actually been studied in a serious way. Most research peptides have very little human data. This one is different: it has a real history as a prescription drug in other countries, several…
Semax
Semax is a lab-made peptide (a short chain of amino acids, the building blocks of proteins) that was developed in Russia in the late 1980s. Doctors there prescribe it for stroke and for problems with thinking and memory. It is not approved anywhere in the West, and most of the research on it is…
