SLOW-RELEASE CAFFEINE (400mg CaffXtend®)
Good caffeine tablets
Good caffeine tablets with slow release. I use the caffeine tablets from time to time when I go training. Good and cheap.

SLOW-RELEASE CAFFEINE (400mg CaffXtend®)
Higher boost
The increase in the amount of caffeine is noticeable, but the extended release does not give me the typical caffeine rush I get with other tablets.

Perfect for me
It's perfect for staying active, much cheaper and faster than walking around with coffees. I would definitely buy it again.

SLOW-RELEASE CAFFEINE (400mg CaffXtend®)
Great
The truth is that it lasts much longer, the normal caffeine gives a peak at once but with this one the sensation is that it lasts longer.

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.

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.
Minimum purchase of units!
