Yup, everyone's different.
I started on a very low-dose and still had bottom growth almost immediately. I was on a very low dose for most of 2017, upped it in January of this year. Seven months in I have quite a furry belly, a slightly lower voice (I had a low voice already), and have had to shave as I don't want facial hair and it's really coming in. I've had a tad more bottom growth, to about an inch - from almost zero when I started. I can't really speak to things like muscles or fat redistribution as I've got too much weight to lose. But, folks have commented that I look good. I'm not sure what it is they're seeing, but I'll take it. Oh, and I get "sir" way more than I used to, though I'm still read primarily as a woman, I think.
So, at about a year and a half on a very low and then low dose, that's been my experience. Good luck!
