Does whey have negative consequences?

if whey meaning whey protein no it doesn't but consuming more then what professionals recommends then it could. i usually consume about 16 oz. 8 oz before workout and 8 after. if you take creatine then be sure to drink alot of water because creatine can damage your kidneys if you don't pee it out. to get better information look in some of the muscle magazines they give alot of information about them or just go to your local GNC and ask.
