Pure Protein bars, Premier 8, and Designer are all quite good, although as with all low carb bars they're loaded with glycerin, of which I'm not a big fan. And Pure Protein uses hydrolyzed bovine collagen as one of their protein sources. Yum. Lean Body bars ain't bad, but they're so loaded with sugar alcohol that they taste like you're drinking a shot, plus they're pretty high in carbs(19g or so)
