According to all breast development studies, amphiregulin is a fundamental growth factor for breast growth/development. Without it all estrogens are useless.

This is why a lot of people here didnt gain any growth using herbs and BO.

This is why AA cup girls can’t see any growth (AA cup, unless you’re very underweight, means failure in breast development) no matter what program they follow.

So, the question is...how to boost amphiregulin?

Interesting Ive never heard this before.... However alot of people here have had great growth including myself, so it must be a lack/stall in development thing or nutrition deficiency thing, remember breasts are mostly made of fat.
