Rule One has just unveiled an all new flavor for one of its many proteins, the sustained release supplement R1 Casein. Previously the product was available in three rather straightforward options, Chocolate Fudge, Strawberries & Creme and Vanilla Creme. The latest from the brand is yet another common recipe with a cookie effort officially titled Cookie Delight. Not only has Rule One unveiled the supplement today, but it has also launched it. Fans of the brand can now pick up Cookie Delight R1 Casein direct from the Rule One website at $37.49 for a 28 serving 2lb or $67.49 for a 55 serving 4lb.
