probably my AI was not enough as the test level kept getting higher in the blood as estrogen did too. i will give it a try and stay on anastrozol for 5 days and see what happens. 4130 ng testosterone you get aromatization i rather have estrogen on range or at least high range that have estrogen on the roof that can’t be healthy. i’ll keep you updated with the experiment. you know everybody is different and when it comes to hormones there is no set rule that works for everybody unfortunately
