Broscience in action: ok... So I heard to take my SizeOn over a periode of time while working out.... sounds like sound advice... or does it? I have read that Creatine turns toxic after about 3-7 sec. after and depending what kind of medium its mixed in .... so why dosnt this apply to SizeOn... I havent read anywhere that it is PH balanced like the Kreacline or what ever its called.
