good shake
plain old Met-Rx shakes are quite thick and good......if you are bulking you can be much more creative with adding in things like skim milk....
ice will always make a shake nice and thick.....
If your bulking, try a Vanilla Met-Rx shake with ice, 1 serving of apple sauce, and some cinnamon......it's like an Apple Cinnamon shake. The apple sauce is basically sugar, so post workout its a good option....adding dextrose is obviosuly good too.
of course, if you're dieting down, you have to live with water and ice....
