Sorry, I skimmed the thread and thought you were already taking 200mg.
So, he had you taking 200mg every two weeks, but now he wants your blood pulled at day seven? That’s because you were at 143 at day fourteen and he wants you to see a better number, which you will, at day seven. That’s just awesome.
Yes, with your rx you are limited to the 200mg over the two weeks. You are looking at 100mg every week or 50 twice a week. I think, given those options, I would take twice weekly. You could go with a 27g 1/2in needle then.
