Semax Dosing Guide

Standard intranasal: 300–600mcg per dose, 1–2x daily. Cycled 2–6 weeks. Russian clinical protocols for stroke recovery use much higher doses (4–9mg/day) but optimization use stays at the lower end.

Blood markers to track

BDNF (specialized)CortisolCBC

Note: Russian clinical peptide. Not FDA-approved. Upregulates BDNF + NGF. Stacks commonly with Selank for combined cognitive-mood support. Short nasal half-life means frequent dosing for sustained effect.
