Thank you everyone for your thoughts and opinions. I'm leaning toward the dymatize elite. It has good reviews, price is good, and 25g of protein. I'm currently bulking and rely on my shakes to add 60 to 80 grams protein a day. I have heard of casein but have never gave it much thought. Would it be worth the extra money to add casein to the mix? If protein is this complicated, then I can't wait to ask about creatine. Lol
