Interesting. I noticed that soy protein suppliments now are not being used by power lifters or bodybuilders. Our gym does not carry it anymore because some of men began to develope man boobs. They never had this problem before and were lean. So it had to be due to the estrogen factor. Soy protein is also an incomplete protein chain.
