Selank & Semax Blend

Also known as Selank Semax blend, nootropic anxiety blend, Russian nootropic combo

A complementary nootropic blend pairing Selank's anxiolytic and GABA-modulating effects with Semax's BDNF-boosting cognitive enhancement. Together they create a balanced nootropic — Selank calms anxiety and stabilizes mood while Semax sharpens focus and drives neuroprotection. Popular in the Russian biohacking community as a daily cognitive stack.

Typical dosing

Half-life
Selank: ~2 hours; Semax: ~2 hours

How it works

Selank modulates GABA-A receptors (like benzodiazepines but non-addictive) and regulates IL-6/enkephalin expression for anxiolysis. Semax stimulates BDNF and NGF production, activates dopaminergic and serotonergic systems, and provides neuroprotection via ACTH(4-7) fragment activity.

Benefits

  • Anxiety reduction + cognitive enhancement synergy
  • Selank provides anxiolytic/anti-anxiety effects
  • Semax drives BDNF elevation and neuroplasticity
  • Improved focus and mental clarity
  • Mood stabilization
  • Neuroprotective from both components
  • Well-tolerated daily use profile

Dosing

250–500 mcg · Once to twice daily

Typically administered as nasal spray. 250–500mcg per component per dose. Can use SubQ. Best taken in morning or afternoon — Semax can be stimulating.

Ranges reflect commonly cited research protocols, not a prescription. Dose with a licensed provider.

Reconstitution

10mg total blend in 2mL = 5mg/mL per component. For nasal use: dilute further to 250–500mcg per pump in preserved saline.
