My E2 and TRT dose story is similar to KeithO's. I'd have to look at blood work from the very first TRT panels to see that.
I've gradually reduced the Test baseline and same with the Adex. Now I'm cutting pills in quarters - originally I took 0.5mg 2x per week. Now it's 0.25mg E3D. And the blood work looks just right, probably will be even better now that I've dropped a smidge to 60mg E3D from 75mg E3D.
Having E2 slightly. Above the reference isn't necessarily a bad thing. It might be worth it to try goin without the adex and see how you feel and what your bloods tell you.
