This is a great breakdown on the different types of protein! A note to other readers here as well, carb content is used as a filler. When you see protein powders aimed at "mass gaining" or "bulking" of any sort, this means they have added a lot of carbohydrates! Remember* carbs make you fat :-)

I just wondered, have you tried using grass fed whey protein? I have heard that it contains 6 X more Conjugated Linoleic Acid (CLA) and Omega 3 Fatty Acids. Its easy to get in Australia, but not sure on Amazon.
