Good
I think it's pretty good...although I don't know how to know how long the effect lasts... I always have energy.

SMART CAFFEINE
Perfect to start the day
I usually wake up and take one capsule on an empty stomach around 06:00 am and go back to sleep, then at 08:30 I wake up with lots of energy to work.

SMART CAFFEINE
Super
Highly recommended for those days when you need an extra "help". The best of all is that it does not have the opposite effect, i.e., it does not activate you and then suddenly gives you a slump.

Caffeine
I prefer them in pills rather than capsules. They open up in my stomach and the caffeine goes up my nose.
