Shot. Right leg. I'm on 200 mg every 10 days now. My doctor said it might work out better for me so I don't feel the lag at the end. Also, apparently my blood iron levels are a bit high. They aren't worried about it, but will check again next time I come in. In the meantime, I'm going to try to stay away from red meats and cereal, as those things have a high iron content.
Just returned from a lovely trip to Kansas with the boy.
