I've been doing this for 3 months now and I'm amazed by the results. A menstrating woman's body produces hormones in varying amounts during her monthly cycle. I have been altering my E and P dose to mimic this for about 3 months now and my breasts have grown a full cup size. It does come with some emotional swings as well as food cravings at certain times of the month. And a bout of hornieness for a few days. My endo said not to do this but I find it works. My breasts are now a borderline D cup and I have been loosing weight/ dieting all the time. If you have flat lined on your development this might be the answer.
