If sure there are plenty of guys in here who lift weights and take protein shakes (not from cocks...from the powder mix). I was reading in Mens Health that some of these protein shakes aren't made of protein but of soy and that increased soy intake can alter the hormones men produce. Some of the side effects are tender breasts, man boobs, increased emotional problems, and emotional sensitivity. Basically, taking these soy products over an extended period of time will turn a guy into a chick with a dick. If you don't believe me check it out on Mens Health's website.
