There’s no discussion. The protein shake is the greatest drink of all time: just ask my biceps. The protein shake not only tastes good, is good for you, and is easy to use, but it makes you HUGE. Go to your local gym and scope out the ten biggest dudes there, I guarantee you every single one of them is either drinking a shake, just drank a shake, or is about to drink a shake. Take a look at Dwayne The Rock Johnson, and tell me that he got the way he is by drinking lattes and juice cleansers… I don’t think so!
