Protica or New Whey Bullets
I've tried the New Whey bullets. The taste and texture is not anything to write home about. But, to get 42 grams of protein in a few swallows...I can tolerate them. (I get the 42 gram bullets and drink about 1/2 of it a a sitting) They are kind of thick and "slimey" is the closest description I can come up with.
I use them when I know I am low on protein for the day.
