Legal statusFDA Approved, OTC SupplementControlled
How it worksCompetitive antagonist at adenosine A1 and A2A receptors (ADORA2A). Adenosine accumulates during wakefulness and signals fatigue; blocking it lifts the brakes on dopaminergic and cholinergic signalling, raises catecholamines, and lowers…Blocks DAT/NET reuptake (without amphetamine's release mechanism) — milder pharmacology, same therapeutic use.
