You gain a few pounds of water weight during the "loading" phase (the entire idea is that it's drawing water and metabolic fuel into the muscles) and then it plateaus as long as you keep taking it. When you stop taking it, the water weight will come off. I workout seriously enough that people notice if that means anything, and I take creatine. It's one of those things with the most proven upsides and essentially no downsides. That said, the effects are nothing like serious PEDs - not that I can personally compare those things, but it's quite clear that gear is a whole other level.
