No shit it didn't do much... Being on higher than normal T likely makes the balance so T dominant that weak poor phytoestrogen doesn't really do anything. Also, what about DHT, that's boob killer number one and usually gym Ahnulds absolutely love it as its kinda beneficial to keep going. Its very effectively halting any feminising changes from happening.
Can't really have both at the same time, the balance is one way or another and E dominance is a certain way of getting rid of muscles and getting fem changes going. I would love to see someone soaked in T being able of growing boobs on NBE stuff, but I don't think its going to happen any time soon.
