I would appreciate if someone could give me feedback on the Optimum Nutrition 100% Whey Protein(2 pound bottle). This is my first time with ANY protein powder. My goal is to bulk.... In all areas, but I'm just so darn obssessed with growth in my biceps.*Shrugs* Don't know why just am. I'm looking at it because I've heard good things about Optimum, and it's cheap online at $15.98.
