Indeed, some scientists believe that this is not just a side-effect, it's the main mechanism by which creatine drives hypertrophy - increased water retention swells the cells, which stimulates them to synthesise more protein. Okay, so it's only me that believes this, but i have a kind of plausible mechanism for it, with tons of experimental evidence for the various steps. Mostly in hepatocytes, but liver, muscle, same difference, you know. Anyway, er, yes, creatine causes a modest but reproducable increase in muscle mass and muscular endurance. There are no definitively established serious side effects - people report all sorts of things, but nothing's stood up to controlled trials. tom -- Operate all mechanisms!

It makes me cramp much faster, even if I drink a lot of water to counter that. Taking magnesium makes the cramping syndrme go away though
