I have not had time to get a full set of labs yet but was wondering what can cause low percentage free testosterone, other than high estradiol? If a person has off the charts high total testosterone (naturally), low estradiol but low to mid range free T. I thought that getting my E2 in check would make my percentage free go up but it did not. My previous blood test showed 894 ng/dl with the top of the range being 824, with a 12 ng/dl free test level (5 - 21 range) and percentage at 1.3% (1.5% - 4.0%). I did not have my estradiol checked but thought it would be high. After testing it recently it was at 11 pg/?l on a < 53 scale. This is after Indolplex/DIM for a week. I went and had another blood test done and this time I was at 915 ng/dl, 11.43 free test, 1.1% percentage. All were the same reference ranges. I did add DHEA 25 mg per day, Zinc 50 mg per day, Copper 2 mg per day, Magnesium 500 mg per day and Vitamin C 1000 mg per day. What could I be doing wrong? What else would cause my Free T to be that low? Thanks.
