I think it depends on what you’re looking for. Do you want a meal replacement, or just straight protein powder? If you don’t like thick shakes, then Grow! may not be for you, although all you would have to do is add more water for a thinner shake, and add the powder slowly while the blender is going so it doesn’t clump up. For straight protein powders, I would give Pro-Blend 55 by HDT a try. It has an awesome taste and isn’t ‘thick’. For a meal replacement, you might want to try Muscle Milk by Cytosport (again, not ‘thick’)…good luck!!!
