An aspect of my ultra male behavior (to suppress the true me) was to bodybuild. At 5'7", I developed 16" arms, a 42" chest, and weighed a trim 185#. I have been on hormones for 50 weeks, and been full time since last Sept. At 5'7", I now weigh 155# with a 40" (B cup) chest. Of course, I have been dieting strictly, and continue to do cardio, and was blessed with a smaller frame.
In addition to muscle loss, I lost most or my strength, but, I enjoy being helpless. (lol) Incidentally, I am 58.
