I've only been on HRT for three months, and while I certainly do not have the amazing curves I'd love to have, there is a noticeable hourglass shape starting to form that even others have commented on without my asking, and I have gained 1" in my overall hip size. I'm not sure the specifics of why some get results and others don't, but perhaps body shape prior to HRT plays a part? I am a very skinny person and was even pre-HRT, so I don't think I had much body fat to redistribute. My theory is that since I've been on HRT, I've been attempting to gain weight so perhaps instead of HRT causing fat to redistribute (as again, there was none), it's simply going right where it's supposed to be. But hell, I dunno.
