Well, I don't understand her reasoning behind what she's saying. It sounds like she's lacking knowledge in this particular arena.
Her idea of prescribing you a topical gel/cream solution is a little crazy because those have a MUCH higher rate of aromatization. More of the test will be aromatized into estrogen, because when you rub that stuff on it has to seep through your skin, and then through your subcutaneous fat. The problem here lies in the fact that aromatase activity is like a hornets nest in fat tissue. Fat tissue is the greatest peripheral source of aromatase. Hence why creams will cause higher estrogen conversion.
