does soy protein really promote estrogen and give guys man boobs
« on: November 18, 2009, 11:58:18 PM »
im intrested in buying a protein blend with whey casein and soy but have heard that soy protein causes estrogen production in men and can lead to man boobs.

Studies are inconclusive, but suggestive in the estrogenic nature. I personally avoid soy. Go with a whey, egg protein blend (Think Pro Complex  :) ) instead.

Two thumbs up for Petey.  Even though tests are disputing each other, why risk it?  If you're shakes however have soy in them as part of their protein profile, don't sweat it.  It isn't enough to make any difference.  I personally won't be scarffing down tofu anytime soon.   :P  (And Pro Complex is still #1)

One of my friends uses soy because he says whey makes his stomach upset (he is super lactose intolerant and it seems like everything makes his stomach upset).  Would you still recommend soy or should he just search for a stomach-friendly whey?

He should use egg, its profile is superior and is great for people who are lactose intolerant

Yup, use egg. Our good friends at Optimum have a top of the line egg protein.

Recent concluded studies have shown, and or proven, that I am not going to get "man boobs" from drinking soy protein shakes. It also offers many other different benefits that whey protein does not and also for me, is much easier for my body to digest and can actually form a real "duece" from it. Whey went through me like water...Certain products for certain people.    Trial and Error.

A lot of blends that IVe taken (Probolic, EAS, etc.) have soy in them, and Ive never considered it to be anything but beneficial. Like DAmmit said, its in such small quantities that it cant hurt you, and there are certain benefits from soy protein. So Im all for blends with soy. That EAS blend from costco for $30/6lbs is a steal and I always keep a bag or two round.
