Slow-release caffeine (400mg CaffXtend™)

Incomparable result

This time-release caffeine is super successful, it allows you to maintain your energy level for at least 10 hours, without the crash of a single dose of caffeine. Great for both training and keeping fatigue levels to a minimum throughout the day. It has a great effect, I recommend taking it in the morning so as not to disturb the rhythm of sleep.

Esta cafeína de liberación prolongada está súper conseguida, permite mantener el nivel de energía durante al menos 10 horas, no tiene el bajón de una dosis de cafeína puntual. Genial tanto para entrenar como para mantener los niveles de cansancio al mínimo durante todo el día. Hace un gran efecto, recomiendo tomarla de mañana para no alterar el ritmo de sueño.

I did not like

I didn't like it, I don't feel the effect at all. I don't know if it's because I have a caffeine tolerance.

No me ha gustado, no siento nada el efecto. No sé si es porque tengo tolerancia a la cafeína.

Best caffeine supplement

I love this supplement, when I take it I feel like I have hours of energy, it doesn't give you a sudden high which I find very unpleasant.

Me encanta este suplemento, cuando lo tomo siento que tengo muchísimas horas de energía, no te da un subidón repentino que me resulta muy desagradable.

Slow-release caffeine (400mg CaffXtend™)

Extra energy supply

I use them before training, when I train early in the morning. I notice how my body is activated for several hours, without having that rush of normal coffee, but it activates you over a long period. I advise if the caffeine does not let you sleep, do not consume it after 17:00h.

Las utilizo antes de entrenar, cuando lo realizo en la mañana temprano. Se nota cómo se me activa el cuerpo durante varias horas, sin tener ese subidón del café normal, sino que va activándote en un largo periodo. Aconsejo si la cafeína no os deja dormir, no consumirla después de las 17:00h.

I'm doing great

I don't like coffee, since it doesn't taste like anything, it's perfect. First thing in the morning I drink it and it activates my metabolism.

A mi el café no me gusta, al no saber a nada van perfectas. A primera hora de la mañana la tomo y me activa el metabolismo.
