doesnt seem to do anything. ive actually fallen asleep immediaatly after taking a few.
i dont think much of any supps though, its real cheap so you could afford to try it your self
i just got some yesterday... since the caffine in it is low, i stacked it today with 150mg caffine... worked great in the area of energy boost and temp. increase... i'll keep using it...
in canada the xenadrine off the shelves sucks though.. this is one of the few products that you can buy, since they market it as a "herbal decongenstant"... (and its about 25 dollars cheaper here)
my xendadrine is on order from the US, but i was all out and needed something to get me through my morning cardio... stacked with the caffine this stuff did the trick for me
