SLOW-RELEASE CAFFEINE (400mg CaffXtend®)
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.

SLOW-RELEASE CAFFEINE (400mg CaffXtend®)
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.

SLOW-RELEASE CAFFEINE (400mg CaffXtend®)
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.

SLOW-RELEASE CAFFEINE (400mg CaffXtend®)
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.

SLOW-RELEASE CAFFEINE (400mg CaffXtend®)
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.

SLOW-RELEASE CAFFEINE (400mg CaffXtend®)
Very correct
The product is what it promises, easy to swallow capsules. The only bad thing is the high price.

Cash.
Prolonged release as opposed to caffeine anhydrous, I usually have both and depending on the day take one or the other.

SLOW-RELEASE CAFFEINE (400mg CaffXtend®)
Very good
It does not give downs or big rises, ideal for the busiest days, it is something different and highly recommended.

Prolonged training
Let's prolong training effectively. I wish it also had taurine, but it goes well with caffeine.

SLOW-RELEASE CAFFEINE (400mg CaffXtend®)
Good product.
They are very effective for studying in those sleepy moments, they keep you active without a slump. I would not recommend them for times when you need a big rush but when you need to be active for a few hours.
Minimum purchase of units!
