I am on 25 mg of something. Real small pill. And theres no way its all muscle mass. Granted 14.8 lbs is alot for a week, and I eat realy healthy. I can definately see the water retention right now, usualy with the creatine I am on I dont get all watery, it doesnt affect me that way. However once they gave me the steriods for my neck suddenly I think I retain a **** load of water.
