It's like how ppl freak out over soy and estrogen. Estrogen is going to make you fat weak and give you gyno.
That's funny because I used soy sauce and soy protein bars during my last diet and I got ripped and was still benching 315.
No food is going to alter your hormones by a large enough margin to make a serious difference as long as you practice moderation.
Green tea has amazing health benefits and there's nothing wrong with having two or three cups a day. If it makes you feel better, put a teaspoon of creatine in one of your cups of green tea because the study say that creatine increases DHT.
