Hey i am fifteen and have a older brother whos 18 i was lookin around yesterday and found a bottle of hydroxycut in his room. He was overweight and i saw a dramitic change in his eating styles and everything else. im a very fit person and work out almost everyday so i kno whats good and not. Now my mom is a nurse and she know about all this stuff and creatine and all the "natural" substances. I kno everyone says there is no after effect but these supplements will burn out your kidney! what should i do sould i tell my mom and let her deal with it or just let it go and see what happens. hes going to college in a couple of days and i kno i cant really control him when hes that far away but he is one of my 2 brothers i have and i dont want him to get hurt in the long run WHAT SHOULD I DO !?

creatine will only have negative effects on kidney and liver if taken in very high doses for a prolonged period of time. make sure your brother is taking the recommended amount, for normal creatine it's 1 teaspoon or 5 grams a day. there is a loading pireod of 20g for 5 days, but im sure hes past that.
