SMART CAFFEINE *
Very good
For those who want pills without too much caffeine, ideal option, since they only have 150mg per intake, but it is noticeable from the first moment, and as it continues for a longer time the slow release. In terms of taste, a normal pill, no more.

Correct
Fast delivery as always, and accessible product with good assimilation. I take it on an empty stomach and before training in the afternoon, it does not affect my sleep.

They work very well
I bought my second bottle as I am in exam time which requires concentration for a long time. It keeps me upbeat all day and I don't get the comedowns I get with regular caffeine. And I sleep great at night.

SMART CAFFEINE *
Does the job
Taken in place of mate and coffee, it seems to do the job, which is handy when you don't have time to prepare everything but know you're going to need an extra boost for the day's objectives.

SMART CAFFEINE *
Ideal for daily use
I took the caffeine and did not notice much difference with regular caffeine. Taken pre-workout with beta-alanine it has a good effect.

SMART CAFFEINE *
Effective
I have been using these pills for over two years and I can say that they are very effective. They keep me awake when I need it and the effect lasts a long time because it is released little by little so it is not a caffeine rush like you might experience when you drink a coffee but it is gradual and it is much better.
