Sure do.
Red Back have a range of 'shakes' including one called WPi (Whey Protein Isolate) ...it has .3 carbs per serving (glass) ..I mix it with water. Tastes better with milk but that's bad ...It also contains all the essential and non essential amino acids. I have been using it for 4 weeks now and have shed 8kgs. It comes in a myriad of flavours (Vanilla Sting is best!)
It's expensive to buy but lasts a life time, works out at something like $5/week.
