You notice its effect from the first day, it helps you on those days when you need a plus for a longer period of time. Good size capsules easy to swallow.

SMART CAFFEINE *
Effective
Although at first it seemed to have no effect, throughout the day I notice that I am not as tired. I take it occasionally, especially if I foresee that it is going to be a tiring day or I have not rested well.
