I'm just under a year in now and have had a fair bit of change, but I dont eat very well so would likely have been more had I dont so. As was mentioned before, I have a few stretch marks, but I think most of them are from before hormones as my actual body shape and fat distribution (aside from boobs) has always been pretty femme for some reason.
I had noticeable effects after less than 4 months (I've taken progress shots every few months on my gallery @
mahkato.deviantart.com if you'd like to see) and now after almost a year I'm certainly budding. I started on AAs just a few months back after being on estrogen since December '06 and since starting AAs I think my body changes have sped up, but I'll wait another couple of months to see that

Oh, and I'll try to eat, thats always a good thing to do
Whatever you do, I hope you are happy with the results
