since your still fairly young, yes your hips may grow out more. Clotting will be a risk for anyone, but excercise and diet greatly reduce them. Don't let yourself sit around all day and make sure you walk a lot, and you should be okay. Also, (someone correct me if i'm wrong) spirinolactone (andro blocker) is also used for high blood pressure, so its use in combination with estrogen should balance out everything. You will want to be on both an andro blocker (pre srs), and estrogen, and from my view point, oral or topical are safer, because needles carry risk associated with cleanliness and proper use. As for bio identical estrogens, I have never even heard of this. you gave me something new to read up on 😛
