Look at some of the breast growers who are trans, it's amazing how some of them have grown, and they have done it despite being genetically male.

Good point. I see evidence there of growth which is surely way beyond any genetically expected size, so it does make me wonder what the maiximum someone can grow to is.

Yes 7 genetic markers have been found and when that was announced I remember seeing an article by a geneticist who reckoned that breast size was 70-80% genetic.

I came across a clinical study on this subject which stated that based on their findings breast size was 56% hereditary.

What do you think is the maximum that someone can grow if they use a variety of methods and take it seriously for many years? Like 4-5 years, or even longer?

There are some trans people who say that they experienced breast growth for up to 10 years.

I've just remembered that Mayusaki also saw a 6 cups increase.

Just a note to say also known as Mayusakimilk.

That's very true in my case I've been on hrt since a child so for many many many years now and still experiencing growth with added NBE, however as I started as a child I have the same possibilities as a natal female breast growth wise as I started hrt well around the time natal women start puberty, I also inherited big breasts from the women in my father's German side though so genetics definitely play a part.

The maximum I've seen documented was 6 cups by Chiyomilk.

I can raise that. I've read of a Japanese woman who achieved a 7 cups increase, from AA to G. I'll find her name and pictures and then you can see if you agree that it's 7 cups.
