It is not effective.
I had high expectations for this product, as the concept is very good. However, I have tried it for several days now and have not noticed any effect. I am not eating it.
Tenía muchas expectativas en este producto, ya que el concepto está muy bien. Sin embargo, lo he probado ya varios días y no he notado ningún efecto. No lo te comiendo.

I do not recommend
I always take caffeine before training and when I tried these, I didn't notice any difference, they hardly have any effect.
Siempre tomo cafeína antes de entrenar y al probar estas, no he notado diferencia, no me hacen apenas efecto

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.
Me da un plus de energía que me viene muy bien si no he podido dormir mis 8 horas de sueño, y no me da efecto rebote de ansiedad o palpitaciones. La uso de forma esporádica y me va bien.

Great
An extra plus for your training and even for studying. I only took one capsule before studying and it was effective.
Un plus extra para tus entrenamiento e incluso para estudiar.

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.
Funcionan y mucho. Más de 12h. Cuidado, si no estás acostumbrado a la cafeína, aunque te la tomes a las 7AM, quizás luego no puedes dormir. Dura mucho el efecto.

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.
Me gusta mucho porque no notas el pico de de cafeina y te pone en estado de alarma sino que notas la activacion a lo largo de toda la mañana.

Works for me
The only thing is that the capsules are a little more uncomfortable than the normal caffeine pills.
Me va bien para estudiar, lo unico que las capsulas me resultan algo mas incomodas que el formato de pastillas de la cafeina normal
