So many choices for protein! Which should I buy!?

Many people have asked me what kind of protein I use. Some weeks I will try to slim down and substitute my lunch with a protein shake. That is 6-8oz of water, or skim milk for more protein, with two scoops of the protein. I have been using GNC's total lean 25 shakes. They are high in protein but low in carbs and sugars. If I am using it after my workout I only use one scoop because I don't need that much protein when I'm finished working out. The point is to minimize calories and amount of carbs while still getting the appropriate amount of protein. This can very though, depending on what your goal is. My only goal is to slim down and build those muscle fibers back up when I'm done at the gym.  The flavors are great and they range from banana, chocolate, peanut butter, vanilla and more. It is a little expensive, so I do have a substitute that I will recommend. You can try and find it for cheaper on a site such as amazon, or you can go with something like muscle milk, which is sold at any Walmart. I would go with muscle milk light powder. They are about equal in calories, and the same in protein. They also have great flavors if you order online: cake batter, chocolate, cookies and creme, peanut butter, strawberries and creme, and vanilla creme; you will have to pay more for online ordering, about $40, but if you go to Walmart you can get the basic flavors for about $22. I hope this was helpful, if your at all confused or have any other questions about protein choices or supplements feel free to comment or email me!
