If you are 135 lbs, I assume you are either an adult female, or an adolescent male. If you are a young male, you should not take creatine, as your body already produces a metabolic creatine amount of about a gram per day. Just like steroids or any other hormone, when you start to add more than your body produces, your body will lower its metabolic production of it. The human body is the ultimate compensation tool. You cannot keep up higher levels than your body wants you to have, for very long. And like testosterone and other steroids, your body will compensate. Take too much steroid, and your testicles will be destroyed in order to keep your levels normal. Creatine? I suppose your pituitary or some other organ will stop secreting the normal amount into your system. The body is the ultimate compensation mechanism, I suggest do not mess with your bodys chemistry.
