Generally speaking, our users and testers report that most of their growth takes place during the first two to four months of using the program, depending on the woman. Some achieve all their growth in less time, and some require more. However long it takes for you to achieve your maximum growth potential, you should use the program for the full six months it is designed to be used, unless you are still noticeably growing when you finish the six month course, and you desire larger breasts than you have achieved by that point.
