Metabolic Drive is $27.99 for ~31 servings. 2 Scoops you will need damn near a whole bottle of water to keep from burning up your blender it is so thick from the high casein content. When I did the V-Diet using the nitrean, I was putting in maybe 1 cup of water to try and thicken it up and it was still thin and not as filling. I love nitrean too and still use it, but when it runs out I will pay the extra money and stick to MD exclusively. The banana rocks and the strawberry is pretty damn good too. I was warned to stay away from the orange, but I got to see that for myself and I haven't tried vanilla or chocolate.
