SMART CAFFEINE
Amazed
I approached this product a little doubtful, I changed my mind after the first week of use, it releases steady energy without the kick of regular caffeine.

SMART CAFFEINE
Complies
It is good to keep you active throughout the day as it is absorbed little by little, remember that for it to take effect you must not have a tolerance to caffeine due to excessive use, otherwise it will not work, better to cycle it.

Product that I use occasionally in times of exams and work, I do not notice the typical high of caffeine but something more prolonged which is appreciated. Quality-price 9.

SMART CAFFEINE
Good product
Slower release than the normal ones, I recommend using the normal caffeine ones by splitting them and spacing the intakes to achieve the same effect as with these for a lower price.

VERIFIED OPINION
SMART CAFFEINE
Works great
I use it in ultra trail races and it works wonders because you avoid the peaks and thus the subsequent drop. It gives you a high and stable activity in the race.
Minimum purchase of units!
