Bobie, honey, I think you can grow breasts simply by beginning a daily regimen of Pueraria Mirifica (PM) and nothing else, at least to begin with. That's what I did. It works for most everyone that's tried it, although the dosage and the rate of progress varies quite a lot from person to person. Figure at least a year to achieve a B-cup size.
I recommend Ainterol R1 PM (find it on Amazon.com) and start out slowly at one or two capsules a day and increasing to 4 or 5 a day over a month's time or until you feel the soreness that indicates that growth is occurring. We call that 'ramping up' so that your body has a chance to adapt to the introduction of miroestrol, the estrogenic compound in PM that mimics human estradiol that triggers breast tissue growth.
You will most likely experience a drop in your sex drive, a loss of spontaneous erections, and a reduction in sperm count. These changes are reversible if you stop taking PM. Infertility is not likely to occur unless you continue to suppress testicular function over a long period of time -- at least a year or two. You may experience erectile dysfunction while on PM. That can be mitigated somewhat by taking cold turkey breaks from PM once a month until your male function returns.
When your breasts grow to the size you are looking for, and that's not a given, mind you, you can drop down to a lower dose of PM to maintain breast fatty tissue. Even if you stop PM altogether, your glandular breast tissue will stay with you. Breast growth is NOT reversible short of surgical mastectomy.
Bobie, good luck on your journey to having a beautiful pair of female breasts. It's going to be an exciting adventure for you.
Huggs,
