Discuss with office managers of the RIGHT doctors. The office managers for my doc are really on the ball and know about all the meds. There's nothing wrong with asking, "Does this doc deal with a lot of cases of hypogonadism, ED, and infertility?" That's what I did.
Most top notch andrologists (urologists with fellowships in andrology) don't do that protocol you speak of though. Mine doesn't, and I've had success with him for nine years. Two other posters here go to him now and feel good. One is actually doing great!
