[The First Aria]

N.R.  For Transgenders actively trying to at least feminize.  Most doctors want the T levels between 25 - 50.  But they can bounce up to 100 and still cause no problems with heart, blood pressure, DVT, stroke and the like, it may slow down feminization if it's not kept at 50 or slightly below.  As long as your Estrogen is between 100 - 200, you are still in the safe range and still should make progress .

For instance....  My Estrogen level at last checkup was 150, but the doctor is concerned that my T is still under 20.  She said she would be happy if my E was 150 - 200 and my T was somewhere between 25 - 50.  She feels that would be my sweet spot, sort of speaking.

At one point, my E was 331, while my T was about 45.  She was happy with my T, but concerned with my E level.  There is something about the difference between T women and CIS women that make E above 200 a danger area.  I think it has to do with the fact that for years we were T based, now we are forcing out bodies to shift to E which is a shock unto itself.

I'm not sure if I can explain it any easier, but you can PM me if you want.  I can try to pass on what I have had to deal with hormone and personally in my last 5- 6 yrs.
