I am currently on TRT for about 4 months now. Doc has me at 200 week which keeps me at 650 (guess I metabolize very fast, low SHBG). Estrogen is right in the middle of the range. Everything seems to be good at this dosage except acne on my arms, shoulders and back. The amount of acne has decreased as time goes on, but is still more than I would like to have (probably about 20-30 small, 10 large at any one time). Anyone else had this experience? Any luck getting rid of it? I've tried the 2 a day showers etc. Tanning isn't an option since skin cancer runs in the family. Thanks for any advice.
