Serious Mass by Optimum Nutrition contains a powerful combination of Whey Protein Concentrate + Egg Albumen that make getting those extra pounds an easy effort. In fact, these two protein types work synergistically to enable quick and healthy muscle grow while allowing no room for undesirable effects.

Whey Protein Concentrate

This type of protein is made of several compounds, including beta-lactoglobulin, alpha lactalbumin, bovine serum albumin, and immunoglobulins. All of these compounds are the building foundations of strong and healthy muscles.

Additionally, whey protein concentrate is excellent for trainers who struggle with their caloric intake and cannot break a certain threshold in regards to mass. The WPC part in Serious Mass will replenish your body’s muscle reserves, leading to more strength, power, and stamina as well.

Egg Albumen

Egg Albumen is basically the white part of the egg without the yolk. This type of protein is perfectly fitting for gaining mass because it contains substantial amounts of protein with little to no fat.

Creatine Monohydrate

In addition to protein, Serious Mass contains Creatine Monohydrate as well. This compound is a groundbreaking force in the bodybuilding industry, because it allows trainers to put on serious mass without risks or any adverse effects. The main benefits of Creatine supplementation include:

  • Gives a significant boost to muscle size and strength
  • Promotes increased recovery rates
  • Improves muscle fibres to better withstands short, explosive bursts of physical activity
  • Improves decision-making and general brain health


No. Serious Mass is safe to use for healthy and individuals over 18 years of age. Please consult with your healthcare provider if you’re eligible of taking ON Serious Mass to gain mass. Do not exceed the recommended dose.


Add two scoops to a blender with 710 ml of water. Blend for up to 60 seconds. Your shake is ready! Note: to achieve thicker texture, substitute water with milk.
