Is there any chance l-citrulline could amplify caffeine? I usually use 9g citrulline malate and don't usually feel a pump with it but do feel enhanced endurance. I'm wondering if the citrulline malate is more malate than citrulline and 2g of straight l-citrulline fields a better effect. Anyone have any experience or thoughts?
