If you are a looking for a routine, there are several threads, do a search or browse around.
One of the most common is PM/SP like this one: http://breastnexus.com/showthread.php?tid=12724
Generally you can't control breast growth, some people have "sprouts" of growth but according to some it reaches plataeus over time and eventually, a maximum limit after many years.
I am assuming you are very young (judging by who you want to look like), please keep in mind this change after a certain point is IRREVERSIABLE. It will also make you sterile after a while, this might not seem important to you at that age but it should be a serious consideration since it's all irreversible.
As for dosage, I would just stick to the standard PM/SP routine dosage from robin, once you get a "sprout" or reach a decent breast growth, reduce your dosage if you do not want further growth.
Please consult with a therapist and GP before starting any routine!
