Just more of the same, from now till you decide to stop!
Growth will almost certainly be slower than you want, but there is no real way to speed it up. Sometimes they will hurt less than at others and you'll start worrying, but sooner or later it will come back again. You'll probably toy with the idea of should you up the dose, or switch to something else, or add something else on top, but if its working then stick with what you are doing, would be my advice, although I do suggest that you play around with how much you take and don't be afraid to try a different level.
The one thing to keep in mind is that what you are doing is permanent. The surrounding fat can come and go, but once breast tissue starts forming it wont go away.
