It MIGHT work. But what are you gonna tell him to run the tests? I suggest you say that you feel really tired, slow, sluggish, you have been working out for a long time and can't seem to get any bigger (you may want to leave this one out if he's seen your progress, or you're already a good size) say you have very little to no sex drive...bla bla bla....tell him that "somebody" suggested to you that you have low testosterone and that you want to have it checked. This MAY work...but, how far away are you from when your cycle ended?
I bend but I do not break.
