what's a protein bullet?

I'm new - had laproscopic RNY on 4/1/08 -- and having trouble getting the required protein.  I keep hearing about protein bullets.  What are they, and where do you get them?

GNC, online, many stores carry these. Some are whey protein, or some other type of protein. They are a "bullet shaped" plastic container, usually clear in color, that contain the thick liquid protein.  Many find the 3 or 4 oz size handy, using half for one portion of protein at around 20-25 grams of protein. Many people pour half of the bullet into an empty water bottle, fill rest with water, and add a comparable flavor of crystal lite to make it more palateble. Just another form of protein.

The brand is New Whey.  They come in flavors:  orange, fruit punch, grape, blue rasberry.  There are two formulas, a 23 g protein and a 42 g protein and are each 3 oz. You can use these with shaved ice and make snowcones. You can use these to replace 3 oz of cold water when following the recipe for jello and have protein jello. You can add ice, pack of splenda, and a little water and make a slushy. This makes it easy to get your protein in. I dont like the taste, however, with just the bullet.  Its thick & strong tasting. You can also add the fruit punch into some water flavored with crystal lite flavor. 

Profect also makes some protein bullets in different flavors than the New Whey. Lora
