Optimum Nutrition (ON) is proud to bring you Pro Complex Gainer - the worlds premier "lean gainer" supplement. Unlike typical weight gain formulas, ON Pro Complex Gainer derives a much higher percentage of its calories from protein. And, while some "ultra-hardgainers" require 1000, 1200, or even 1500 calorie/serving weight gain products, many athletes can gain quality mass with considerably less. So, in addition to calories, ON Pro Complex Gainer provides a blend of 6 premium protein sources, complex carbohydrates, dietary fiber, lipids, digestive enzymes, vitamins and mineral.

Suggested Use: Add 1 heaping scoop to about 16 oz of cold water and shake or blend for 45-60 seconds. For a thicker shake try mixing Pro Complex Gainer in a blender with milk and ice.

Pro Complex Gainer is a superior mass-gain supplement that can be used to support high-protein and high-calorie needs in a variety of ways:

Between Meals: Drink 1-2 serving(s) between meals to encourage a positive nitrogen balance and support a high-calorie diet.

Post-Workout: Drink 1 serving of Pro Complex Gainer 30-60 minutes following exercise to support maximum recovery. Receiving proper nutrition post-workout is paramount...don't neglect it!

As a general rule, consume approximately one gram of protein per pound of body weight per day, split evenly over 5-7 meals and/or supplements.
