First off you won't be building much muscle without working out all of your big muscles.
You should incorperate some heavy compound lifting into your workout that include your back and legs which you seem to be lacking.
Try some bench press, standing military press, deadlifts, squats and barbell rows as the base for your routine and add any other exercises you like.
I dont now much about supplements, I only take whey powder, so mabye you can ask in the nutrition section.
Hope that helps you out.
