Biggest mistake people make is thinking the drug doesn't work if they don't get the shakes. Completely false. I take 40mcg along with T3 and it melts fat away very nicely. The drug helps to burn an extra 300 to 350 calories per day. One thing to remember is if you don't have a clean diet and thinking Clen is going to make you lose weight no matter what you eat, you are going to be disappointed. Extremely powerful and effective drug when used properly and very dangerous when abused.
