Super
I bought this for my 18 year old son who is a student. He often sleeps through the night and is out of action the next day, so I got him this to test it out in view of the excellent reviews. Well, I'm not disappointed! Right from the first dose, he saw the effects. It combats his fatigue and makes him more focused. He only takes it when he needs it though.
J'ai acheté ça pour mon fils de 18 ans qui est étudiant. Il lui arrive souvent de faire des petites nuits et donc d'être HS le lendemain, alors je lui ai pris ça pour testé au vu des excellents avis. Et bien je ne suis pas déçu ! Dès la première prise il en à vu les effets. Ca combat sa fatigue et le rend plus -concentré- Il est hyper content. Il n'en prend que quand il à en besoin par contre.

Very good
I love this product, I take it on those days when I need an extra boost of energy and it feels great. It doesn't make me sleepy at night and doesn't leave me over-activated.
Me encanta este producto, lo tomo esos días que me hace falta un extra de energía y me sienta muy bien. No me quita el sueño por las noches ni me deja sobre activada.

Personally I like the normal ones better
Personally caffeine in 200mg tabs have worked better for me than these, but everyone is different.
Personalmente la cafeína en tabs de 200mg me han funcionado mejor que éstas, pero cada persona es distinta.

Effective
For when you don't want the typical caffeine high, this is the solution. It activates you less but for longer.
Para cuando no quieres el subidón típico de la cafeína esta es la solución. Te activa menos pero durante más tiempo.

It works
The days that I have taken it, I have felt less tired, and stronger at the gym. I don't know if it will be more effective than regular caffeine. I only take it on leg days and sometimes on chest day. It had expired on me and I still noticed the effects, maybe if I had taken it earlier it would be even more functional, I don't know.
Los días que lo he tomado, me he notado menos cansado, y con fuerza en el gimnasio. No sé si será más efectiva que la cafeína normal. Sólo la tomo en días de pierna y algunas veces en día de pecho. Se me había caducado y aún así he notado los efectos, quizás si lo hubiese tomado antes sería más funcional aún, no lo sé.

I have very little
I have been taking them for a short time and I can't evaluate them very well yet. I started taking them for my competitive exams and it is noticeable.
Llevo muy poco y no puedo valorar muy bien todavía. Las empecé a tomar para la oposiciones y algo se nota.
