Starting a strict gym schedule tomorrow. I'm 5'9", 150 right now. My goal is to gain mass. I have protein, which I'm going to do two shakes a day with. I also take a multi every day. Now I'm confused about two more. Creatine and Glutamine. What are the two best rated products with these supplements? Is there a hybrid of the two? Should I be taking these three? How often? thanks guys!
