Hey, i take NO2, it's working pretty well for me, and i like it, you dont have to cycle it at all and you can use it with other supplements like animal stack etc..... i hear a lot of people cdomplaining about it but its not to bad for me, its is supposed to be esspecially good when you are on ur cutting cycle, (which i am now). I take 5 pills 30 minutes before brekfast and 5 before lunch, it is not going to bring you wonders of anykind but its is pretty good for the kind of product it is, but if you ask me it is not worth your money because you can get some legal ger for the same price...... but i would recomend you to try it, if it doesnt work just bring it back !
