Who it's for

Cognitive-performance researchers studying BDNF / NGF modulation, focus, and neuroprotection.

Key things to know

  • Intranasal administration provides rapid CNS uptake.
  • Effects appear within 30–90 minutes — cognitive task pairing is common.
  • Cycle 4–6 weeks on, 2 weeks off to preserve receptor responsiveness.
  • Pairs well with Selank for combined focus + anxiolytic profiles.
Research Highlights
  • Used clinically in Russia for acute ischemic stroke and cognitive disorders
  • Multiple studies show BDNF elevation within 90 minutes of administration
