SMART CAFFEINE *
Activation without anxiety
It gives me a plus of energy that comes in handy if I have not been able to sleep my 8 hours of sleep, and it does not give me a rebound effect of anxiety or palpitations. I use it sporadically and it works well for me.

Great
An extra plus for your training and even for studying. I only took one capsule before studying and it was effective.

Great
The best caffeine on the market for your workouts, to study with more concentration and efficiency, and to wake up on days when you need an extra boost.

Careful that they work
They work very well. More than 12h. Be careful, if you are not used to caffeine, even if you take it at 7AM, you may not be able to sleep afterwards. The effect lasts a long time.

Very good.
I really like it because you don't notice the caffeine spike and it puts you in a state of alarm but you notice the activation throughout the morning.

Good
Very good presentation with the bottle. They are really effective if you don't want to drink coffee, therefore recommended.

Works for me
The only thing is that the capsules are a little more uncomfortable than the normal caffeine pills.

Caffeine.
I have not taken it yet. It was going as a free gift for purchase over X. I intend to use it on very long work shifts so I can't yet assess if I will be up all day with just one capsule.
