Cognitive

Cognitive Enhancement & Focus Stack

Semax and Selank are the most clinically researched peptides for cognitive enhancement, with decades of published study behind them — genuinely rare in the peptide space. Semax raises cognitive bandwidth by increasing BDNF and improving cerebral blood flow, while Selank keeps the stress response regulated so performance pressure doesn't undermine output. The result is calm, clear focus qualitatively different from stimulant nootropics — no jitteriness, no crash, no dependency, delivered intranasally for rapid CNS uptake.

Protocol & Dosing

Standard Protocol (5 days on / 2 days off):

  • Semax 0.1% solution: 2 drops per nostril (≈200 mcg total) each morning
  • Selank 0.15% solution: 2 drops per nostril (≈250 mcg total) mid-morning, at least 2 hours after Semax
High-Demand Protocol (intensive periods):
  • Semax 0.1%: 3 drops per nostril twice daily (morning and early afternoon)
  • Selank 0.15%: 2–3 drops per nostril twice daily
Cycle: 4–6 weeks on / 2 weeks off

Notes: Store intranasal solutions refrigerated at all times. Rotate peptides if using long-term to preserve receptor sensitivity. Avoid caffeine within 1 hour of dosing to avoid CNS overstimulation.
