SLOW-RELEASE CAFFEINE (400mg CaffXtend®)

Super

They come in super handy for those days when I need that extra. If I know it's going to be a hard day, I take one of these capsules in the morning and I know that I'm going to train. The good stuff, the best stuff.

Me vienen súper bien para esos días que necesito ese extra. Si sé que va a ser un día duro, por la mañana tomo una de estas cápsulas y sé que iré a entrenar sí o sí. De lo bueno, lo mejor.

Caffeine

With these capsules as an ergogenic supplement in endurance and ultra-endurance competition, you forget to calculate when and how you are taking your doses of caffeine. Being time-release you take it before the test, or if it is more than 8 hours, two shots, and you forget about it. Format much more economical than other commercial brand sold in pharmacies, which is what I used to use before.

Con estas cápsulas como complemento ergogénico en la competición de resistencia y ultra resistencia, te olvidas de andar calculando cuando y como vas tomando tus dosis de cafeína. Al ser de liberación prolongada lo tomas antes de la prueba, o si pasa de 8 horas, dos tomas, y te olvidas. Formato mucho mas económico que otra marca comercial vendida en farmacias, que es el que usaba antes.

Very interesting

I've only had time to take it for two days, but it works! It keeps you more alert for 10-12 hours, it doesn't give you the high like normal caffeine, it's like the feeling of being well rested and having more energy.

¡Solo me ha dado tiempo a tomarlo dos días, pero funciona! Te mantiene más espabilado durante 10-12 horas, no te da el subidón como la cafeína normal, es como la sensación de haber descansado bien y tener mas energía.

A great experience

The caffeine I was looking for. It gives you that spark you need throughout the day. I just take one in the morning with my breakfast and I've already managed to get rid of my morning coffee. It works very well.

La cafeína que buscaba. Te aporta esa chispa que necesitas durante todo el día. Solo tomo una en la mañana con mi desayuno y ya he conseguido deshacerme de mi café matutino. Funciona muy bien.

Good quality

You notice the caffeine softer but more prolonged in time, it is not something for 1 hour workouts but after that you notice it, if you take it at night you do not sleep.

Notas la cafeína más suave pero más prolongada en el tiempo, no es algo para entrenos de 1 hora pero a partir de eso se nota, si lo tomas por la noche no duermes.

Wonderful

It is the caffeine that has the most effect on me when I need extra energy for more hours. You don't notice the high and low peaks. It keeps you active for several hours but without altering you.

Es la cafeína que más efecto me hace cuando necesito extra de energía durante más horas. No se nota el pico de subida y bajada. Te mantiene activo bastantes horas pero sin alterarte.

Immediate activation!

I thought that the activation would be smaller, but it is true that it has enough hours of activation and leaves you electric. Good product for those who do not want to abuse coffee, like me, I take it in the morning.

Pensé que la activación iba a ser más pequeña, pero es cierto que tiene bastantes horas de activación y te deja eléctrico. Buen producto para quienes no quieren abusar del café, como yo, que me lo tomo por la mañana.

Very effective

It works for me both for concentration during the study day and during training, which is as if it becomes more active as I become more active. It's also worth the time release because the other normal one gives you a more sudden peak of intensity. Great product.

A mi me sirve tanto para la concentración en el día de estudio como en el entreno, que es como si se activase más conforme yo me activo. Además merece la pena ésta, de liberación prolongada porque la otra normal sí te pega un pico de intensidad más repentino. Productazo.

Very correct

The product is what it promises, easy to swallow capsules. The only bad thing is the high price.

El producto es lo que prometen, cápsulas fáciles de tragar. Lo único malo el precio elevado.
