Good
Best, one capsule between 9 and 11 o'clock. Desired effects and does not interfere with sleep or wear or stain teeth. Rest a day or two weekly to maintain its effectiveness and not generate tolerance.

Good product
It does its job, it gives you extra energy and concentration to face the study day, but I have not noticed any difference between normal caffeine anhydrous and this one.
