I like it

Posted by odereviews on Jan 15, 2013

This is better than the caffeine or taurine for boosting my training days. I haven't noticed any side-effects. Although I don't take these daily, so my body doesn't build any tolerance. Great guarana product with a cheap price.

Definitely an energizer

This stuff is certainly potent, at least it is to me. One pill wakes you right up and keeps you energized for a good seven hours, with a very gentle tapering off at the end (you don't even really realise it's wearing off, unless you pay a lot of attention). This is certainly helping me get through many long nights of school work followed by long days of classes.
