your probably right there for Grondar's situation.
Grondar: It sounds like what you want is a meal replacment drink instead of a protein shake.
A replacment will still have good levels of protein, but will contain all the essential vitamins and minerals that your body needs, especially if your going more cardio than pure bulk.
A protein shake will just give you protein, great if you want to bulk, but you can't drink a few each day and expect the gains that regular meals would give you.
AST Ny-Tro Pro-40 is meant to be quite good, i'm planning on getting a box when i have the cash.
a place with good articles on the subject is
www.bodybuilding.com, they have miles and miles of archives that will help you out.
remember, unless you do plan on doing some serious working out and do want to bulk, then protein suppliments are really unnecessary.
