I am on a low-carb eating plan & bought the Vanilla powder & WPI (Whey Protein Isloate Powder. The WPI is supposed to be very high in protein & v. low in fat & carbs. I made a milkshake of it in the morning & didn't feel hungry for hours, so the quality is there. I also didn't have any allergic reaction - seems pure. They kept me informed re the ETA, the packaging was great (vacuum packed zip-tip bags, so economical to store, easy to use. Will I use these guys again - you bet!

Approximate cost: $168
