Are you asking if you should take Protein or creatine?

Protein is a must if you are working out. Min is a 1.5g per lb of body weight.

Another must is BCAAs.
make sure you take some BCAAs 30 minutes before workout with a protein shake and a shake right after workout. Try to eat a small meal afterwards too.
