Enhances high-affinity choline uptake (HACU) via a unique mechanism distinct from other racetams — it increases HACU even in damaged cholinergic neurons, suggesting a choline uptake enhancement rather than mere stimulation. This HACU enhancement persists even after the compound has been cleared, indicating a lasting modification of choline transporter activity. Also shows affinity for AMPA receptors.

Contains oroxylin A — a flavonoid that inhibits PDE (phosphodiesterase), increases BDNF, and modulates dopamine signaling. Enhances focus and motivation without stimulant side effects. Also acts as a mild MAO-B inhibitor, preserving dopamine levels.
