I take HCG 350 iu on Thursday and MOnday sub-q (behind the upper arm) And TestCYp 60 mg on Friday and Tuesday also sub-q( in stomach). Till two weeks ago I was taking both as IM. The sex drive has vanished, I wonder why, I have lots of fat in my stomach area though or does it take time? When should I check the peak testostone and estrogen coz I can order some tests from discount lab. I was asked by defy doc to do sub-q. I want to avoid and AI. Both as IM (test cyp in butt area and HCG in arm muscle area was working but the estrogen was 58 even on the second day from taking test cyp.
