Since you obviously have an internet connection and access to the web, why don't you use them for some research? Information about creatine abounds — some accurate, some slanted toward sales of supplements. Here's one that's neutral.

Incidentally, much of what you said about creatine that you're "pretty sure" about is incorrect. It has little to do with muscle mass, as you'll learn if you look around through information on ther web.

i have heard from multiple sources that it puts tons of water into your muslces thats why you must drink so much extra while taking it. that explains the sudden decrease in muscle mass when you stop taking it. yes it dehydrates you it recomends drinking liek a gallon of water a day while taking it…..personally i wouldnt take it…stick to protien shakes they will do about the same and the muscle wont decrease if you stop taking it
