Slow-release caffeine (400mg CaffXtend™)

Caffeine

I take 1 right after waking up instead of the typical cup of coffee that gives me heartburn and its effect is smooth and linear for several hours. In contrast, coffee is immediate and in my case it gives me acidity.

Tomo 1 justo después de levantarme en lugar de la taza típica de café que me produce acidez y su efecto es suave y lineal durante varias horas. En contraposición, el café al uso es inmediato y en mi caso me produce acidez.

Very good

It is the caffeine that I like the most because it takes effect soon after taking it and it is long lasting. The capsules are small, odorless and easy to swallow. Highly recommended.

Es la cafeína que más me gusta por que hace efecto al poco de tomarla y es duradero. Las cápsulas son pequeñas inodoras y fáciles de tragar. Recomendable totalmente.

It is well

When you are very tired and if you are not very used to it, it is time-released.

Cuando estás muy cansado y si no estás muy acostumbrado se nota mucho es de liberación prolongada.

Ideal as a pre-workout or on days when you are half out of energy. The activation effect is very noticeable.

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.

La verdad que funciona muy bien pero, tienes que tener una cierta tolerancia a la cafeína o, no haberla consumido por otro lado. Te activa tanto que hay que cuidar el no haber tomado ninguna otra cosa pero bueno, su función la cumple a la perfección.

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.

Tomé anteriormente las de 200mg. Y sí me daban energía. Compré 400mg y me dan el efecto contrario. Me siento muy cansada y me dan sueño.
