Selank vs Semax
Both are nootropic peptide compounds. Here's how they line up on the evidence — graded the same way.
| Selank | Semax | |
|---|---|---|
| Evidence | 6/10 | 6/10 |
| Class | Nootropic peptide | Nootropic peptide |

Selank
Selank is a lab-made peptide (a short chain of amino acids, the building blocks of proteins) that was developed in Russia and is sold online as an anti-anxiety and "nootropic" (brain-boosting) compound. There is real human research behind it, but it's thin, almost all from Russia, and done on small…
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…
