CNS Adenosine Antagonism Grade A Human RCT Evidence
Caffeine Anhydrous / Sustained-Release
Clinical analysis covering biological pathways, optimal timing, and human trial dosing requirements for sports performance and body recomposition.
Human Clinical Efficacy Dose
150mg – 300mg (3–6mg/kg)
Dosing below this threshold demonstrates statistically diminished outcomes in randomized trials.
Primary Performance Mechanism
Elevates mental focus, central nervous system firing rate, and peak anaerobic sprint velocity.
Mechanism of Action
Competitively binds to adenosine A1 and A2A receptors in the brain, reducing perceived exertion (RPE) and increasing motor unit recruitment velocity.
