After 1 year of anti-androgens and a small dose of estrogen, my muscle mass has decreased, but not quite where I want it to be. Muscles on my whole arms have shrunk considerably, even though I would take a bit more. My thighs, though, not quite. But I'm beginning to think if there was a bit less fat there, the muscle might not look as bad. So once I'm full-time and comfortable with showing myself exercising, I think I'll do some aerobic exercise in the lower body. Actually, if I have the money, I could even buy a new DDR game and mat, and ask my sister to send me back the family's Wii.
...Say, is playing Dance Dance Revolution aerobic or anaerobic exercise?
I haven't been doing anything special. I'm vegetarian, which may have helped, who knows, but I'm also eating pretty wrong overall, so I don't know. I'm probably still anemic, for example. I'm taking cyproterone, though, not spiro, and my testosterone is at 0.5 pmol/L, which is in the lower range for women.
In short, not exercising and eating vegetarian might do something, but seeing the state of my thighs, not so sure. I think the main factor is going to be your testosterone levels.
