After around a year and a half of using the regular estradiol blood test with my TRT regimen, i came back with 4-5 results always around 20-27 pg/ml (7.6-42.6). I just received the results from an estradiol sensitive and the results came back at 6.3 pg/ml (8-35). So as most of you are aware, the estradiol sensitive is the correct blood test to use for males, but like me and many others, I was misinformed by life extension that the regular estradiol test was sufficient. We need to petition LEF to change their website. That is all, and I hope I can save some hassle for the next person who gets misinformation.
