My body's "baseline" is zero, my Leydig's cells no longer function to produce FSH/TSH, which is the expected outcome of a decade of AAS use.

Bloodwork from no Testosterone usage puts my T around 90ng/dL, or the upper end of female reference range, and my E2 at the bottom end of male range.

Hence, TRT as a medical necessity.

  > I'm assuming that's unrelated to the values in your post because there is no way that 200mg/week produces those numbers.

Yes, those bloods were on 1,500mg/wk.

  > I also really, really would not recommend that any men try to keep their E2 at 3X the upper end of the reference range.

Certainly not unless your T levels are proportionally x2-3 reference range. The T:E2 ratio is wildly important.
