Summary
Phenylpiracetam is orally bioavailable (~100%) with a 3-5 hour elimination half-life. Unmetabolized drug is excreted 40% via urine and 60% via bile and sweat. The R-enantiomer functions as a selective dopamine transporter inhibitor, conferring genuine stimulant properties. It is the only racetam banned in competitive sports by WADA due to performance-enhancing effects. Users consistently report clear mental energy at 100-200 mg, but tolerance develops rapidly after 2-3 consecutive days.
