If you need an extra boost of energy, this is the product for you.
I'm studying, working and doing 1.5 hours of exercise a day at the gym. There are times when I don't sleep well and the day ahead is so intense that I was looking for something that would give me extra energy, but without the side effects of drinking a couple of coffees: palpitations, nervousness? I came across this option and the truth is that I couldn't be happier to have bought it. I take a capsule on days when I need extra energy and it works perfectly. I notice that the tiredness goes away, that I am more active, more awake and ready for whatever the day has in store for me. All this, without side effects or anything like that; what is true is that if I need that "shot" of energy in the afternoon, I usually take the capsule before 18h. It has no taste and the convenience is that you can take it wherever you want and take it when you need it. Of course, I usually do not take it every day because we know that the body gets used to it quickly and then asks for more, but taking it every other day works great for me. An excellent option.

Essential
For me an essential supplement in my daily life. Not only for the extra energy but also for the activation effect. I recommend that if you stop noticing the effects do not increase the dose. Take a two-week break from caffeine and that's it.

Perfect for study
The combination of theanine with caffeine in this ratio is perfect for use in times of exams or oppositions, because the addition of theanine reduces the feeling of nervousness typical of caffeine and also allows greater concentration if you know how to keep focused on a single task.
