CONSISTENCY

Optimum Nutrition has been spotting the efforts of goal driven individuals since 1986. As one of the few companies to own and operate state-of-the-art manufacturing facilities that are GMP compliant and NSF Certified for Sport, ON assures that every shake will mix up effortlessly because the company started instantizing powdered products back in 2000. You also expect each shake to taste the same as the last and your next. That’s the kind of consistency ON delivers.

 

HISTORY & HERITAGE

Optimum Nutrition is legendary for both quality and innovation. In addition to producing the world’s best-selling whey protein, ON’s Gold Standard 100% Casein introduced slow-digesting nighttime protein to the weight training world and Amino Energy created the anytime energy category in sports nutrition. When technology makes advancements possible, ON will be the company bringing it to you.

    How to mix
    I tried mixing according to directions - way too thick. I use only 1 scoop mix with 2 cups of milk tray of ice (important) bit of chocolate syrup ice cream (1-2 cups) and mix for 45 seconds. Makes a whole blender drink it before I go to bed. Much easier and better tasting this way than the 2 scoops recommended.

    Very Effective
    I'm a skinny guy and I don't have a very big appetite one thing I like about Serious Mass is that I can mix one scoop with a shaker of water 3 times a day at work it's very smooth and easy to drink. I've gained 15 pounds of muscle in the last 2 months.

    Great meal replacer
    I drink two scoops every morning bc I simply don't have time for breakfast. It tastes excellent but you definitely need a shaker with the whisk ball in it to make these. I even replace other meals with this when I have to but it's very cost effective! I order a ton up front and it lasts me months.
