Depends on a lot of things, mainly how good of a doctor you have. If he/she is good, they will do a full work up on you and do a complete panel. They will then see low LH and low FSH. They will think you've been abusing steroids or have a pituitary tumor. Also, if you do a typical 8-12 week cycle, your hematocrit and hemoglobin will be elevated and they will see that too. That will be another thing they freak out about. Also, aramid ex can mess with your cholesterol profile.
Now, if you have a sloppy doctor, they'll just check total testosterone, see it's low, then prescribe you some Androgel or Testim. If you're lucky, they might prescribe testosterone cypionate (but those docs will probably do a full panel).
Also, don't talk about 'how you can put on muscle.' That is an immediate sign to any doc that you're looking for a script for steroids. Don't even talk about Nolva, SERMS, hCG, etc. right there that'll tell a doc that you're looking for drugs. Talk about lack of energy, dick don't work, tired in the afternoon, lack of interest in sex, etc. Depending on your doc, you might get Androgel or you might get Viagra and some antidepressants.
As you can see, it's not very easy, especially with the insurance company. How old are you, by the way? If you're older, late 30's and beyond, it's easier than someone younger
