TOS 8 permits you to discuss drugs but as far as recommending one, there are far to many factors. Your physical health, your blood test results, the availability of drugs where you live and possibly insurance coverage. Normally what happens is your therapist recommends you to an Endo. The Endo will run blood test and make sure the drug will be safe for you and check your T levels. If all is good you will receive a small prescription and near the end of it, your T levels will be check again. If a dosage adjustment is required, changes will be made other wise you will receive another prescription. The idea is to give as little drug as possible to do the job. It's also possible the doctor will decide on a long term injectable drug where you will receive injections from the doctor as needed. It eliminates pill taking but it is more expensive.
Unfortunately there is no one best drug. Each has it's advantages and disadvantages so the doctor will need to decide on the correct drug for you.
