my breast development took a little longer than most people on here. in the first few months there was a little soreness once in a while but it would go away pretty quick, but then starting in like late october (3 months into HRT) they started to get sensitive and they stay a little sore now.
for the muscle loss, I don't think I've really lost much yet, but I noticed that my energy went down a lot and I think that's because of the spiro. I have a pretty physical job that has a lot of lifting, and I've been off work since early November but I'm going back to work tomorrow for about 2 weeks, so I guess this will be a good test to see how much strength I've lost lol
