I've spent a few years on this site reading countless stories of females taking various amounts of certain herbs and spices over several months and achieving differing amounts of temporary and permanent breast growth. And after researching the old methods of initiating a pseudopregnant state with hormone injections to treat hypoplastic breasts, and after studying the progressive growth, and lack thereof, of the breasts of pregnant females, the sum of the matter seems to be that breast growth in an XX chromosome female is directly proportional to her individual sensitivity to various endogenous hormones.

We know that the estradiol and progesterone levels of pregnant females are usually at least 100 times higher than their menstruating levels, not to mention their levels of other growth factors like human growth hormone, IGF-1, hepatocyte growth factor, epithelial growth factor, etc., yet there are countless pregnant females that experience little to no breast growth. The majority of breast growth in a pregnant female is visible around the second trimester, when her estradiol levels are 5,000 to 15,000 pg/mL, and her progesterone levels vary between 50 to 280 ng/mL. These levels exceed menstruating levels exponentially, yeah there are many females that see little change in their breasts during this time. These levels also exceed anything possible with herb or spice intake, yeah we find some females that achieve great growth of their breasts by taking these foodstuffs.

The users of this forum are taking modest amounts of common plants and glands, with very few of them experiencing dramatic breast growth, and most seeing little to none. Reading the reviews of birth control at drugs.com reveals that some women increase their breast size by two cups without gaining weight elsewhere, while others see little change or find themselves gaining appreciable size in their lower body.

Why is it so common to find that females who are bottom-heavy have modest, even flaccid, breasts whose growth is resistant to reasonable levels of steroid hormones? We find both the fat and the lean to present with all measures of breast size. We see gestating females of all kinds displaying wildly various amounts of breast change during their gestation. 

Is not all of this ultimately due to individual variations in steroid hormone sensitivity? For how else can two similar females take identical amounts of the same birth control medication and yet experience dramatic differences in their breasts? How else can some pregnant females have enormous increases in their steroid hormones and growth factors, yet see little breast change, while others multiply their breast size two or even three-fold? 

Should we not be more focused on finding methods to modify existing chemical sensitivities, rather than only increasing these hormones or their doppelgangers?

Funny you mention this i was pondering something yesterday my intial question was as a 'thin/athletic build' naturally, how do i get fat to store in my breast? I googled various things and stumble across this;

Long story short body building article talking about receptors particularly alpha-2 (stores fat) whereas beta breaksdown lipids, they say this is why you can trim down and still have areas of fat due to receptor density and senstivity. They go on to talk about certain product that targets the receptors and shut them down helping burn those stubborn fat areas, this is true for myself its love handles;  am considered under weight by bmi calculator but i have small love handles. 

Then i found this body building forum suggesting same thing regarding receptors.

Then this 
https://www.davedraper.com/article-134-hormones.html

He talks of insulin and glycogen which 'i think' bind to these receptors and how increases cause by certain things and foods cause certain events followed by good old cortisol.

So yes i think its more about receptors then hormones...i say it on my thread as well however i was talking about E now it may be more then that. It may be receptors that store fat that need to looked out. 

Ive in the past told many i didnt think E dumping was helpful for growth, Lotus seemed to share my view as found much literature on low doses of herbs that increase E eg fenugreek and flip side too much desensitizes receptors. Lotus also suggested we had enough progesterone as women and as too armotase potential and high prolactin was unhelpful for breast growth so what does it leave with receptors sensitivity and availability. It may explain why one BN member can do a routine and grow breast and another can try and get nothing or gain weight else where because receptors are shut down in breast and/or available and dense in other areas. 

So what does it leave you with? Waking up receptors. 
- which ones 
- how (i know a few)
- is it safe

All questions to ponder for now.
