Who Uses PRO Complex?

Mike Rigoni

“There is no better bang for your buck protein on the market. It contains some of the highest quality protein sources for anabolic support for hours after training. The vitamin blend has also been replaced with BCAAs and Glutamine which is a much greater value to the strength athlete who's looking for an extra edge.”

Tobias Young

“Pro Complex is my favorite every day protein. I love the fact that I not only get whey, but also egg protein, and BCAAs all in one product. Add the fact that it contains hydrolyzed whey and egg protein you know you are getting super high quality with minimal lactose or other impurities. The protein mixes super easy with a spoon and the taste is on point!”

Optimum Nutrition Quality

At ON we are proud to know that we are one of the few sports nutrition companies who own and operate their own production facilities. While it's true that ON is one of the world's largest producers of sports nutrition products, we remain focused on being recognized as the best. In fact, our requirements for raw materials are so strenuous that it's not unusual for ON Quality Assurance Technicians to reject entire truckloads of raw materials that do not meet our high standards. We like to think that we take as much pride & care in crafting our award-winning supplements as our consumers do with crafting their physiques and fitness accomplishments.
