You just hit the nail on the head. Many young BB'rs believe that the more you take, the bigger you'll get and everything will be okay - without getting themselves tested for liver, blood, and heart as they go along. It's true, these side-affects don't occur over night but they do occur. If you are using juice, don't be afraid to go to the doctor and get tested for everything. Instead of being afraid, you should WANT to have your levels checked.
