Mixing Directions: Using a Blender: Healthy Adults Only: Mix 1 serving (140 g) with 8 - 20 fl oz (240 - 600 ml) of cold water, milk or other beverage and blend to desired consistency (more liquid helps reduce thickness for easier mixing). Using a Shaker Cup (Use More Liquid Per Serving): Healthy Adults Only: Mix 1serving (140 g) with 8 - 24fl oz (240 - 720 ml) of cold water, milk or other beverage and shake up to desired consistency. For Best Mixing Results, Do This: 1. Add liquid. 2. Then powder. 3. Blend/shake. Tastes amazing in water - tastes even better in milk! Always add liquid first, then add Mutant Mass.

Warnings Do not use if packaging has been tampered with. Do not use if bag is torn or open. Keep out of reach of children.
