If I stop taking creatine?

Ok, first muscle does not turn to fat. Muscle is muscle fat is fat, the only way muscle gets smaller is to stop working out, hence if you stop working out fat cells will begin to get larger. Creatine has nothing to do with you working out, or really getting stronger, it only aids in repairing you muscle after it is damaged from lifting. And honestly you piss out most of it anyway, you are doing a good job working out if you are seeing results.
