Sheesh, people want it all at once. YEARS, it will take YEARS and there is nothing you can do to speed the process up, like ever. your Endocrinologist will find the perfect combination of medications for "YOUR" body and "YOUR" transition which will deviate from other people's experiences. It took me ten years, A FREAKING DECADE to get my boobs. TEN YEARS! Breast growth has to do with a host of variables such as genes, how far after puberty HRT was started, what and how much sex hormones and anti-androgens are taken, how much prolactin your body produces, growth hormones, ect. What you take is ultimately up to your doctors, but you should be well learned in these areas and you can go to more than one doctor. Second opinions happen daily.
