I was thinking about picking up some cell mass and read alot of good reviews on it. I researched and found the only real side effect is being bloated, but that is also more related to creatine monohydrate not the ester. Once you cycle off of it, they also say you will lose a good amount of weight. How much weight is typically lost, and do you then cycle back on after a short while? Also any side effects that you guys know of that are not typically posted online?
