"The Nootropic Duo"
Enhanced focus, anxiety reduction, neuroprotection, mental clarity
Semax provides potent cognitive enhancement and BDNF upregulation, while Selank delivers anxiolytic effects comparable to benzodiazepines without sedation. Together, they create calm focus — enhanced cognition without overstimulation.
Semax upregulates BDNF and neurotrophin expression for cognitive enhancement. Selank modulates GABA/serotonin for anxiety reduction and stabilizes enkephalin levels. Complementary pathways: nootropic + anxiolytic.
Typical Ratio: Semax 200-600mcg + Selank 250-500mcg per dose
Both administered as nasal sprays. Semax AM for focus, Selank AM/PM for anxiety. Can be used together or alternated. Cycle 4-12 weeks.
