Ok looks like you got a lot of tips on how to lower his test before getting bloodwork. Im guessing you dont need to worry about that as he is probably already low.
IMO the first mistake people make is trying to work with their normal doctor regarding testosterone therapy. You are much better off to deal with an HRT Clinic. They specialize in this. They are fast, and affordable.
If you want a great contact at an HRT Clinic, PM me and let me know. I have a buddy that works at a clinic and Im sure he would be glad to help you out.
