The truth is that it works very well but...
The truth is that it works very well, but you have to have a certain tolerance to caffeine or not have consumed it otherwise. It activates you so much that you have to be careful not to have taken anything else but, well, it fulfills its function perfectly.

No effect
I previously took the 200mg. And they did give me energy. I bought 400mg and they give me the opposite effect. I feel very tired and they make me sleepy.

Effective
They are super effective. They keep you energized during the day and at bedtime there is no problem. If you open the capsule it has a slight coffee smell and the texture is grainy.
