Hi,
I'm over 50. I'm still changing. It just takes time. For the length of time you have been on higher dose HRT, you are doing fine.
As far as HRT regimens...most doctors start low and ramp the dose up over few months. I have heard of the start the dose very high and then lower it down. The first way is safe but slow while the second way is faster, there is greater risk. In the end, after a few years, one ends up at about the same point. Then, after SRS or at least testicle removal, changes start again.
You are getting there......
Hugs,
Jen
