None - I don't jump through hoops. This doctor doesn't own your body, doesn't own your health, and doesn't own the right to decide anything except what she's going to do. She is the one that needs to jump through your hoops if she wants to keep you as a patient. Talk to her, tell her how you feel and what sort of treatment you expect to get.
If she doesn't respond in a way that you're comfortable with, thank her for her time and go elsewhere.
It also helps to have your guns loaded when you talk to her. Is she right? Are you functioning normally? Can you "present" with the symptoms of low test? Your blood results are just a number.
If you're just curious about how you would feel at higher levels, then very few doctors are going to help you. The Life Extension Foundation has a list of doctors you might try.
With the wealth of information available on the internet, you can know as much or more than she does about testosterone if you study up. The Society for Endocrinology publishes it's protocols. Being able to talk knowledgeably about the subject with her will get you better responses and will probably help you feel less like you need to jump through anyone's hoops.
She's also bound by the law. Have you read the Anabolic Steroids Control Act? Did you know that she can be prosecuted as a drug dealer if she isn't careful?
Don't get me wrong, I'm on your side, but your side is a tough one to defend and you need lots of ammo. My test came in at low normal and my doctor told me "no way" when I asked about TRT. My functioning was "OK." But I was simply curious how I would feel at higher levels so I read everything I could find and devised my own treatment plan and I self medicate.
I'm now around 850 and "OK" went to "Great!" Unfortunately, the law and public perception make it very difficult for older men to feel great. We're supposed to be satisfied with OK. If you're not, I doubt that jumping through hoops is going to make you feel better.
