Protein Drink??
I'm going on the cheap now and using HDT which only costs $49.95 for 6 lbs at www.netrition.com . It has to be blended with a blender. However, I had been using Syntrax's Pure Essence vanilla which can be mixed with a spoon. All of the Syntrax products can be mixed with a spoon and come in many flavors.. You can look up protein powders by type or manufacturer at netrition.com. I sometimes buy elsewhere, but I can compare products there and look at the labels. Just be aware that they cater to both body builders and to people who are trying to lose weight. Look for powders that have high protein and low carbs.
