Hey Sunshine,

PC is still a mystery to me. Many in the feild of medicine believe PC does nothing with breast growth. But I truly believe its a synergystic component for growth when one is deficient. If you are not Progesterone deficient, you will need some form of estrogen to offset growth.
Since you don't have an idea.
I would get a hormone saliva test kit I think they are $99. You take the test at home and then send it off to the lab. Its very accurate and will tell you exactly what your hormone levels are for testosterone,estrogens,progesterone and DHEA. I found out and knew that anything estrogenic was a no-no as they were high.
The only reason why I recommend testing is because my first attempt five years before gave only temporary results and then gave me androgen dominance with acne and manshaping from the phyto estrogens turning into DHT.
You can totally guess and try either or butyou could be waisting time, money and make yourself worse off.

There are online tests that can give you an idea if you are estrogen deficient or dominant. Beware some of the symptoms are similar.

NBE is trial and error so I like to minimize the trial and most of all the error part of it if I can.
