I've not used protein shakes (or any other supplement) in a long time. Not needed them. 
Starting this week though I am on a heavy cut, so wanted a protein drink I can use to stow the carb pangs once or twice a day. This was the best they had in the shop (only 2.2g carbs per serving, but 42g I think protein.) It's nice but surprisingly small serving. I'm used to having to guzzle at least a pint in one go, not a thimble full.
