Protein Shakes cause liver damage and such. (It warns you about it on the can)
PS: facetrain yourself.
I Believe they already have this, Its called "Imagination". I Agree with you a LOT of people drink this crap, and yet they don't understand not only is this bad for your health, but after about 2-3 months of not working out they will deflate. My advice to you is build up naturally, eat a lot of protein, and forget about that protein shake crap.
