hey whats up? i have taken about 2 diff bottles of the no2. you need to take either 4 in the morning before you eat atleast 30min before and 30 min before lunch the key when taking it is to drink tons of water if you dont you wont see many resluts. i havent gained any weight on it just have seen a little of the perpetual pump but stop wasting your money trust me i have taken enough to know and think about doing the real stuff.
