Developing muscle is more about how much protein you are getting and how heavy you are lifting and working out to break the muscle down. Protein shakes help with recovery, but not all people swear by them. I personally started using them to make sure I was getting enough protein in the day - it's a convenient way to do this.
I am liking the BSN-Syntha 6 that has fast and slow release protein throughout the day. So, my system is getting protein at various times.
I drink one in the morning as soon as I wake up and right after my weights workout (within 30-60 minutes). These are the best times to take them to help heal and prevent muscle from starting to break down.
Just buy a container of a brand you want to try and start throwing them in and see what you think for a few months. It won't hurt to try.
