Just so we're all really clear, no herb or plant extract has progesterone in it. PM and other phytoestrogens have estradiol mimics, but they do not have estradiol or either of the other two estrogens that are normally present in humans. Humans also don't have the enzymatic pathway to convert the progesterone precursors found in some plant sources such as FG. So take as much FG or RC as you want, but it will do nothing for your serum progesterone levels. Whatever effects you notice from them comes from another path or substance, but NOT because they contain progesterone or your body makes progesterone from them.

And lastly, as far as I understand it, permanent breast growth is going to come from glandular tissue development along with the fat deposits that support them. Estradiol or a phytoestrogen mimic are mainly responsible for breast growth. In natal females progesterone is responsible for the final development of the alveoli which are lined with milk producing cells, but don't contribute significantly to overall breast tissue proliferation. Progesterone also causes water retention which can affect breast size temporarily and is the primary culprit in PMS symptoms. In men, progesterone is converted into testosterone. So, do you really want to increase your serum progesterone levels?

Hope this helps.
