I actually WON a contest that Xyience was running at a local VitaminShoppe here in town - got their entire line-up. I did try the NOX, and to be honest, it was not that bad. You will never hear me say the word "PUMP," but it did provide me with some sort of skin-tightening, some added energy, with no stomach discomfort. If it's cheaper than what it usually is, grab some...
I ended up giving it all a way, except NOX.
