My point was your actual testosterone levels are much higher than the tests indicated since you got them done an entire week after you rlast injection. That point is the exteme trough of your serum levels, and you were still over the range.
You sound concerned about the long term risks of high testosterone, so the fact that your labwork basically paints an inaccurate picture should be of concern to you.
Estrogen should be kept down, but IMO so should your test--you should not be that much higher than the lab range (which you actually didn't provide and I'm just speculating on what it was) one week past your last injection. Your actual average T Levels could be as much as 150% of the indicated value!!!
I personally have no problem keeping test REASONABLY above the range since I feel that the ranges are slightly skewed to the low end (due to the fact that more sick people get blood tests than do healthy people), but I am undecided on how much higher is "reasonable".
If you feel great and your other health indicators are fine, then this may be the range for you.
You didn't mention other health markers, so that should be used as a guideline. You also never mentioned SHBG, your actual E2 values, and Free T (which will be lower if SHBG and E2 are high). If your doc is not monitoring these values, and only your Total T, then he is only mildly educated on TRT and has some learning to do.
To answer your earlier question, reducing E2 probably won't affect your serum T levels at all (since all your T is now exogeneous) but it will impact your Free T levels slightly (increasing them).
