I'm going to politely disagree with asking for a number for your test to be at. I think you should give it the 2 months and then judge by how you feel whether your dosage needs changed. The BW is helpful but you may feel great at 600 and like crap at 1000. You may be side effect free at 600 and have to deal with E2 issues at 1000. The blood work will let you know where you are but only you can tell how you feel.
Although your blood level may be up after 2 or 3 weeks it may take longer than that for your body to adjust to your new level.
