Not sure bovine & poultry hormones can make humans over-develop, but can't imagine they're good for us either. Although a little different, steroids are hormones too & look at the havoc they cause when misused. Cancer, weird physiology changes & sexual problems, etc.
yes i think it does. girls are starting their periods earlier and earlier. 'they' say its because of better nutrition, but i seriously have my doubts on that theory. i think these hormones that are being used are finding their way into our bodies and into our enviroment.
