I use one that I LOVE from GNC. The brand is ProPerformance. I can't remember the exact carbs but I think, it's around 4-5, per serving. You can mix it with water and ice, and it tastes amazing. It's also very filling. They have alot of flavors, but the chocolate one is great. I use my martini shaker to mix it up, but you can stir it with a spoon too.
