bro, i've tried noxplode. aside from the mega dose of stimulants, the product is garbage. way overprice for what you get. and the only thing with any quality to it in the product is the creatine- which if you do the math comes out to some ridiculous price per serving. like Suareezay said, why pay over $40 for a few dollars worth of actual product. as far as the no2 part of the mix, it does absolutely nothing as far as gaining mass or strength. in fact studies show that the long term use of products like this can be detrmential to your health.it is a better choice to spend your money on somethin that is proven to work- like food, protein, more food. if you feel like you need an extra boost, good ole' coffee works just as well for about .05 a cup. cant beat that. if you have any more questions do a search- there are about a hundred threads debunking the whole no2-noexplode bandwagon.
