I was working with Dr. Lam. At that time, the price was much lower than 1000. Did you call him? Dr. Lam listens to the symptoms, your story. If you decide to call his office, write down what you would like to mention. After a few weeks on his program he asks to do a salivary test. sometimes he asks for blood tests (iron studies etc.) He uses his own formulas available at supplementclinic.com
