Hydroxylated piracetam analog. Slightly more potent than piracetam; mild stimulant profile distinct from aniracetam's mood profile.

ABSORPTION-RATE PROVENANCE: this value was derived by inverting the one-compartment peak-time relation in 2026-05-26-wave25-ka-from-tmax.ts, whose header claimed every peak time was verbatim from a primary human study. ALL FORTY-FOUR ENTRIES HAVE NOW BEEN CHECKED AND TWENTY-EIGHT FAIL. This one fails because the midpoint of a verbatim "peak levels within 1-2 h". It is DISCLOSED RATHER THAN DELETED: a midpoint of a narrow range is usually inside the true spread, and removing it would fall back on the solver default of 1.0 per hour, which is worse for most of these records.
