May have benefit: Many trainers i know use them and many do not. They won't hurt you but i would avoid those which contain stimulants such as caffeine. Read.The label and make sure only Amino Acids are in the ingredients.

Muscle building: Muscle are composed of protein, so when stimulating muscle growth through weight lifting, it is essential to have protein in your diet. This can be real food, or supplements.
