So everything in my blood panels look great, I'm on 100 mg a week of test cypionate split into two doses .50 each a week. E2 lc/ms is 23, Total T he also ran as Lc/ms and its 589, Free T was 27 shbg was 24. He told me today he wants to cut my dose to .75 a week because my bioavailable testosterone was in the 200's. I understand Total, and free. I also know I feel great where I am right now. Can anyone explain what the big deal is if my "Bioavailable Testosterone" is high?
