Directions For Pro Complex:

SPOON STIRRED: For each scoop of PRO Complex®, add 4-6 oz of cold water, milk or any beverage with a complementary flavor. Because the powder has been instantized, all you really need is a spoon to stir the powder into a delicious protein shake.

SHAKER CUP: Bringing a shaker cup along to the gym presents you with a quick, easy way to produce the perfect shake every time. Mix each scoop of PRO Complex in a shaker filled with 4-6 oz of your preferred beverage, screw the cap on tight and shake for a few seconds.

ELECTRIC BLENDER: Using an electric blender, you can turn a serving of PRO Complex into a fresh fruit smoothie and/or stack this protein shake with Creatine and other sports nutrition ingredients. TIP: Adding a couple of ice cubes can improve the consistency of your shake.

SUGGESTED USE: For healthy adults, consume enough protein to meet your daily protein requirements with a combination of high protein foods and protein supplements throughout the day as part of a balanced diet and exercise program.
