i heard it had androstene in it

Hey, don't waste your money. It's all marketing hype, and the worst thing about it is they are using the guys name who discovered creatine to push this garbage. I wasted over seventy dollars for a bottle of this crap and all i did was fart more. Just the mere fact that GNC cornered the market on the original NO2 should indicate it is a scam.

70$ for ONE bottle??!
I paid 25$ 100g of HPLC l-citrulline [ i must say it's a good product and i'm satisfied however please forget hyped ad claims ] and 41$ a bottle of Ox by San.
Irrespective of the product, shopping wise is the key...
otherwise vendors all ride Porsche & we ride grandpa's donkey...

this stuff is ass. And it makes u smell like ass
