It activates me a lot. Great
I decided to try it because I am very low on energy and concentration. At the moment I only take one capsule in the morning, and it works spectacularly well.

I did not trust this product but it works
I have noticed very significant improvement in my rest this week that I have been using it. I didn't have much confidence in it but it is working for me personally.

Good product
I decided to try this product based on the reviews and I have to say that I am satisfied with it. I arrive late in the afternoon still energized without needing to take a nap after lunch.

It helps me to concentrate a lot
This is the second time I have taken it in preparation for exams. I have a hard time concentrating and with this product I am able to sit for longer periods of time, concentrating on my studies and not on anything else. I was hesitant to buy it, but I am very happy. It helped a lot in previous exams and that's why I bought it again. I only recommend it for specific periods as it contains caffeine.

Acceptable
It does not have a great effect but it is a good complement to others. A bit expensive compared to the effectiveness.

It works
I don't know if it's the placebo effect or what, but you feel more energetic and able to concentrate.

Help for periods of high stress
I use it for periods when I need to give a final push to my studies and I notice that I am more concentrated and I don't get distracted by anything as I usually do.

It helps me.
My concentration and information retention improved to 100%. I take it around noon because with the morning coffee and the caffeine dose that the product has, my heart rate goes up a lot.

It fulfills its function.
I am preparing for a competitive examination and the truth is that it helps me to stay studying longer.

Helps to be more alert
It helps to be more alert and, curiously, reduces the craving for food (I don't know why). It is a bit expensive, but it is noticeable. I reserve it for when I need to be more focused and more lucid in my work (systems, telecommunications).
