My TRT HCg + nolvadex

Hello, Ive been running TRT as requested from my doctor at 5000 IUs of HCg once per week and 20 mg of nolvadex (now tapered down to only 10 a day). I understanf that 5000 is way too high but I finally found a doctor thats willing to help me without going bankrupt and my parents will not support me. I feel stuck with every doctor giving me bad guidance. I took a test for my free testosterone a couple days ago and it was very high (around 0.84 nmol/l) reference range is 0.19-0.62. I feel the same pretty much in terms of symptoms go and i suspect my estrogen and prolactin levels are way too high. Should i switch out the nolvadex to arimidex?
