Did you ever have your estrogen levels checked before you started T? Maybe 'high' estrogen is where your body is used to operating. It may have little to do with the dose of T you are administering but rather the time on T, and that your body has not yet been able to suppress the estrogen production. It took me a few years on T for that to happen...strong ovaries and pituitary, I guess! And even then, I needed a hysto to correct that and a few other problems. If your T level is appropriate at your dose, then I would say it might be too early to expect less estrogen to be circulating. Our bodies try hard to maintain homeostasis, but eventually the T will become dominant. My doctor suggested lowering my dose and injecting more frequently to help this process along, so the body gets used to having a more steady level of Testosterone. Personally, I would avoid taking any other medications to remedy this, since it may not even be a problem... Patience is a BIG requirement with transition!
