          Great Casein Powder

          Good tasting Casein protein powder.

          Provides the extra protein I need.

          A bit difficult to mix at times, but worth it.

          Great Taste, Mixes Well

          This casein is easy to mix, tastes great, and is easy on the stomach. It keeps me full for hours. Highly recommended.

          First of all, great taste! Didn't spot any undesirable body reactions, all goes well.

          Also, the powder dissolves really easily when shaking or steering.
