You can still get changes even after 5 years. I've been on hrt over 10 myself. I have no idea what your surgical status is or if you plan on it or not, but I know some have said they got more changes after their testes were removed.
Me, I've only got barely a cups and a size 8, but then I started at 40 and am slight in build, even my sister isn't much bigger in cup size than I am.
