I posted this study in 2015 to show the importance of having progesterone in your program. The takeaway here is that without progesterone while taking estradiol and anti-androgen breasts don't mature. Meaning the alveoli, breast ducts and breast buds don't develop to tanner stage 5 potential.
In another study an assay of human male hormone receptors in breast tissue found the following (and this in regards to each being equal to 100%, not the total of the three being @ 100%, follow?).
Breasts
Estrogen receptors @ 94%
Progesterone receptors @ 93%
Androgen receptors @ 57%
So, in human male testes we have the following productions:
Testes
Testosterone @ 85%
Estradiol @ 15%
Anti-androgens inhibit T/DHT between 30-90%. When T is lowered to 50ng/dL and below its considered chemical castration.
So this is how my thinking goes:
Use progesterone cream to reduce T/DHT in breast tissue.
And in the testes reduce that testosterone of 85% to 5 to 10% using an effective anti-androgen that inhibits @ 80%.
Simple, right?. I believe one could tweak these numbers to how they wish to proceed. Meaning some don't want breast development while others do. We just massage these numbers to create a small imbalance favoring feminization but no breast development, I would do that by just using progesterone cream on the breast...no PM (or estradiol) and an anti-androgen titrated to 45-50% or flip the script geared towards breast growth, and titrate even more for the full feminization.
