How it works

Phenylpiracetam is a potent derivative of piracetam used clinically in Russia for cognitive decline, stroke recovery, and physical stamina. Human evidence is largely limited to Eastern European clinical trials, showing significant benefits for mental fatigue and focus, though it is banned by WADA for athletic competition due to its stimulatory effects.

It acts as a selective dopamine reuptake inhibitor (DRI) and increases the density of acetylcholine, NMDA, and GABA receptors while improving cerebral blood flow.

Safety

  • May cause insomnia if taken late in the day.
  • Rapid tolerance development often requires cycling.
  • Banned by WADA for use in professional sports.
