Potently stimulates high-affinity choline uptake (HACU) in hippocampal synaptosomes, the rate-limiting step in acetylcholine synthesis. This profoundly enhances cholinergic neurotransmission without direct receptor agonism. Approximately 10-30x more potent than piracetam on a per-milligram basis. Does not significantly affect other neurotransmitter systems, making it a highly targeted cholinergic enhancer.

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.
