Quality Mass Through Premium Proteins and Nutrient-Dense Calories!
Optimum Nutrition 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 minerals.

Big gainsLove Pro Gainer. Taste isn’t decent. Lots of protein per drink major help kn hitting my daily needs to gain muscle mass. Some days it is just hard to find the time to eat the kinds of meals i want so dropping in a protein shake helps out when i am on the go.

Awesome GainerI drink one shake after my weight training sessions. Helps to get 3500+ a day and maintain lean muscle mass. This is a highly recommend staple for those who train seriously.
