The doctor will probably want to measure your starting values to know how much of each drug is required. It's very possible the blocker isn't going to be required and sometimes the estradiol levels may need to be adjusted depending on what your body naturally produces. If you self medicate the doctor isn't going to know the starting values and may say you don't need treatment or give you less than you need. If you don't self medicate, the doctor will have a much better idea what you need and will get it right the first time.
