Ok hope the combo is working for you, I discontinued the PM when I started the bi-est though. The PM was definitely working on breast development after a month or so but wasn't feeling too good on it and was a little alarmed with how fast the growth was, I'm not really as interested in breasts as I am with feminizing the rest of my body, not that I'm against it happening just wanted to focus on one or the other, bi-est or pm. Bi-est definitely works but have to say the PM alone seemed to do more for breast growth compared side by side for a month in my case, maybe because I was more consistent with it.
