Optimum Serious Mass vs Pro Gainer

Both Optimum Nutrition's Serious Mass and Gold Standard Pro Gainer are designed with the primary goal of supporting muscle growth and recovery. They're tailored for those looking to bulk up, with a focus on providing a substantial amount of protein and calories. Serious Mass packs a hefty 1250 calories with 50g of protein and 252g of total carbohydrates per serving. In contrast, Gold Standard Pro Gainer offers 60g of protein and 81g of carbs. While Serious Mass leans more towards a higher calorie count, Gold Standard Pro Gainer emphasizes a slightly higher protein content. Additionally, while both products boast a blend of quality proteins, Gold Standard Pro Gainer includes enzymes like Carbogen® and Aminogen® to aid digestion.

We recommend Optimum Nutrition's Serious Mass, but only by a tiny margin. The primary reason for this recommendation is its value, especially considering its lower price point. While both products are exceptional in their own right, Serious Mass offers a more affordable option without compromising on quality or effectiveness. With 1250 calories, 50g of protein, and a comprehensive vitamin and mineral blend per serving, the value you're getting with Serious Mass is hard to beat. It's an excellent choice for those looking to gain mass without breaking the bank. However, it's worth noting that if protein content is a higher priority, Gold Standard Pro Gainer does edge out with its 60g of protein per serving.
