Since someone posted the BB.com thing, please search that forum(ignore the pigs) for why muscle milk is a horrid product on many levels, besides the all out fat content the main concern of mine is arsenic.

Anyhow, I use NOW Whey Isolate. You aren't paying for flash advertising and it has absolutely NO fillers, just straight whey if you go unflavored(which I do but it comes choco & 'nilla). It's instantized so it mixes with a spoon, no grit. Use it in anything, however when adding to warm items go the 'cornstarch technique' but mixing with cool liquid then add it in.

Works really well in regular fruit juice and smoothies, all in all a nice base at about 105 cal, almost no fat, basically no sugar, think 5g carb if that, and 25g protein per scoop so budgeting recipes to get the desired macros isn't too much of a pain.

FWIW.
