Nootropics

Phenylpiracetam

Evidence: moderate_human

Mechanism of Action

Atypical dopamine reuptake inhibitor with additional phenethylamine-like stimulatory properties. Increases the density of acetylcholine, NMDA, GABA, and dopamine receptors in the brain. The phenyl group addition to the piracetam backbone enables blood-brain barrier penetration at 20-60x greater potency than piracetam, with added psychostimulant and cold-tolerance properties.

Dosing Protocol

Standard: 100-300 mg/day divided into 1-2 doses

Maintenance: 100-200 mg/day

Administration: oral

Timing: Morning or early afternoon; avoid evening use due to stimulant effects. Take with or without food.

Duration: Use sparingly — tolerance develops rapidly. Best cycled 2 weeks on, 2 weeks off, or reserved for acute-need situations.

Notes

Banned by WADA — athletes must be aware. Tolerance develops within days of continuous use, making it unsuitable for daily supplementation. Best reserved as an acute performance enhancer for demanding days. The R-isomer appears to be primarily responsible for the nootropic effects while the S-isomer drives the stimulant properties.
