Optimum Nutrition's Serious Mass features an exclusive weight gain formula with creatine and glutamine for strength athletes. It includes proprietary protein blend, maltodextrin, creatine, glutamine, inositol, choline and essential vitamins and minerals. Serious Mass provides large amounts of quality calories, protein and creatine to optimize each strength training workout and develop a powerful physique.

Serious Mass contains 50 grams of whey protein concentrate, calcium caseinate, egg albumen and sweet dairy whey. This proprietary blend promotes protein synthesis and maximum nitrogen retention (stored muscle protein) The addition of conditionally essential amino acid glutamine supports protein metabolism and promotes muscle gain, repair and recovery.

Creatine is a naturally occurring metabolite found in muscle that can increase muscle mass, energy, strength, endurance and recovery. Maltodextrin's protein sparing complex carbs replenish muscle glycogen (energy stores) and help regulate blood sugar levels.

Choline is a precursor of the neurotransmitter acetylcholine and helps support energy, memory, learning and muscle contractions. Inositol is part of the vitamin B complex and can enhance hormonal balance, alleviate overtraining, promote immunity and decrease recovery time


Serious Mass delivers 50 grams of high quality protein, 1 gram of creatine and 1250 calories per serving. Combined with an energy-rich diet and intense physical activity, Serious Mass helps support the development of a powerful physique.

Serious Mass has the following benefits:

  • 50 grams of high quality protein promotes muscle gain
  • 1 gram of creatine increases muscle size, strength and endurance
  • Choline and inositol support strength training
  • Glutamine promotes muscle repair and recovery


People who are allergic to dairy products should avoid whey protein.

Few side effects are associated with glutamine supplementation. However, mega-dosing with glutamine over an extended period of time may result in potential side effects such as diarrhea, weakness and nausea.

Stomach upset, diarrhea, nausea, bloating, dehydration and muscle cramping have been reported with creatine use.

With larger amounts of choline (several grams daily), certain people may experience a fishy body odor, abdominal discomfort, diarrhea or nausea.
