Finally something that works

I suffer from Chronic Fatigue Syndrome (CFS) and I've tried many things without success. Since I received this I take it together with Maca and I swear it works! I don't feel jittery or anxious and I'm not as sleepy during the day. I feel more fresh when I wake up aswell.

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.
I like it

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.
