Semax dosing does not map onto the injection-and-units model used for most research peptides, because it is given intranasally and its dosing comes from the Russian products where it is registered rather than from a Western clinical guideline. There is no FDA-sanctioned dose.[1][2]
Reviewed for accuracy · Last reviewed July 7, 2026In Russia, Semax is registered for uses such as ischemic stroke and cognitive recovery, and the dose depends on the specific product and indication. Community nootropic use cites various intranasal amounts, but these are extrapolation. Because the underlying efficacy evidence is predominantly preclinical and largely Russian, treat any specific figure as poorly validated for healthy-person cognitive use.
