SLOW-RELEASE CAFFEINE (400mg CaffXtend®)
Well
Since it is an extended release, you don't feel that punch or immediate effect, it's a different sensation. In theory you are more concentrated during the day...

SLOW-RELEASE CAFFEINE (400mg CaffXtend®)
Effective
Good value for money. The capsules are good and can be swallowed well. You can feel the constant stimulation, without the downs like when you take a typical energy drink. At the latest I take them at 11:30-12h in the morning. I recommend them without a doubt.

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.

SLOW-RELEASE CAFFEINE (400mg CaffXtend®)
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.

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.
