Pro Series




MUSCLES ARE MADE BIGGER AND STRONGER // with weight training and amino acids from protein. How much protein depends on your size, your training and your goals, among other factors. PRO Complex is the formula for big-time athletes with even bigger aspirations. We augmented this stack of superior quality proteins with BCAAs and L-Glutamine to add even more to your recovery potential.




PUTTING ON SIZE // requires a balance of heavy training and quality nutrition. Because everyone’s a little different, some have a harder time packing on muscle than others. PRO Gainer is a high-protein formula delivering calories that count during recovery. Each shake provides ample supplemental protein, carbs, vitamins and minerals to build on the amount you’re getting through a balanced diet of food. PRO Gainer makes a great post-workout recovery shake or nutrient-dense meal between meals.




THE BRANCHED CHAIN AMINO ACIDS (BCAAs) // are valued by active adults for their anabolic and anti-catabolic qualities. Used in a 2:1:1 ratio of Leucine to Isoleucine and Valine before and
/or during endurance exercise, they may help spare muscle tissue. Used after strength training, BCAAs help kick-start protein synthesis which plays an important role in muscle growth. ON’s advanced formula includes 5 grams of glutamine because this conditionally essential amino acid may help support recovery after intense training.
