If you want a pure protein goodness without the fillers and all, Lush by far is the best. I've purchased a few from iHerb and other sites - some has fillers, some don't. Having purchased from Lush for more than 6 yrs (I think), these are what I've gathered: 1. They require more scoops for the same amount of protein that Lush offers; 2. Those with fillers especially - just made my tummy feel less than optimum. Gives alot of bloating feel and I don't feel good most times when I take them; 3. Lush has less sugars (you can choose the unflavoured ones anyway) 4. Price is reasonable!
