I am only interested in building the chest muscles.
Yes it will , but not as magically as you would like. The body will process the protien you take in and put it where it needs it most. So , you work out your chest and have well balanced protein , you will build your chest.
caution, if you are only working your chest, you should not be adding a lot of protien, your body does not handle protein overload very well. Many protien shakes and bars for body builders have 60-90g of protien, for your chest only, you should limit it to 20-30g after your workout, in addition to your daily protien.
