I had budding with just herbals...as I understand it, both men and women have T and E....obviously males have more T, and females more E...but the body operates with both, hopefully in the correct ratios. With AA usage ( = less T simulates a higher E in the ratio) one could see some developments.
Imho
And yes, the breasts are independent of each other, I will have an itchy breast on one side, then the other. Yay! π
