Yeah, that was Chris Duffy who ate nothing but protein drinks - couldn't have been healthy but he was in awesome shape.
I'm using Pro-lab stuff just now because it doesn't have aspartame. Also got the Lebrada, Weider and EAS ready to drink stuff.
Recommend the new Myoplex Storm protein bars, taste like Snickers but they do have a bit of sugar in them - 27g of protein however. I like the Dorian Yates bars too, but they've got aspartame in them too.
