True Strength is a journey. It never rests, it never quits. It’s about overcoming obstacles, accomplishing goals, and recognizing achievements. And then it resets to achieve again. As your trusted sports nutrition partner in goal achievement, ON demonstrates that same passion while crafting our products. From the raw materials we source to our state-of-the-art manufacturing processes, no compromises are made.

Serious weight gain requires serious calories. However, those who need the extra calories most often have the toughest time consuming enough of them. For many aspiring to be bigger, a highly-active metabolism, weaker appetite and on-the-run lifestyle can make it a real challenge to consume enough calories through whole foods alone. With Serious Mass™ – Vanilla, you’ve got nothing to lose and lots to gain. We’ve consolidated 1250 calories, 50 grams of protein, 253 grams of carbohydrates, 25 vitamins & minerals, glutamine and creatine into every serving. It’s time to stop thinking small; get serious – Serious Mass™.
