Okay, feel a bit of moron now because I spoke too soon, operating on assumptions. Testosterone DOES convert estrogen in its excess, but excess estrogen (yes, I looked it up, so no more misinformation) simply causes overfeminization of the body, as well as potential migraine headaches, weight gain, and excessive fluid retention. So yeah... if you want to have bigger breasts, more extremely felt emotions, and what may seem like a permanent state of PMS, estrogen shots are the way to go. They still won't change your feelings about being a woman (or lack thereof).
