Testosterone competes with estradiol over sex-hormone receptors. Therefore, the more you have, the less estrogenic effect on the body HRT will have. Your skin will stay fairly masculine, breast development will be minimal, your body odor will be AWFUL (mix of E and T is just nasty... my roommate is going through that), body hair will continue to grow normally, muscles may or may not atrophy but probably not dramatically, you'll probably gain mass in areas that you will NOT like them(around the middle), while also gaining some in the thighs but at a larger rate than normal because your T is mildly suppressed (T helps with maintaining body weight), you'll probably see an increase in subcutaneous fatbecause E is responsible for that, but since the T is still there the skin will be a bit thicker than it could be, making the skin less translucent and more fatty (pretty bad combo)
High T for women is a bad deal...
Oh... and also, if testosterone induced bone growth in the face hasn't completed, that will continue.
