Optimum Nutrition Serious Mass in Strawberry delivers 50 g of protein per serving across 16 servings per container, which works out to 800 g of total protein per tub. Each serving is 334 g of powder, mixed into water or milk.
Its Value Score is 11 - a Value Score under 70 is below the category average - you are likely paying a brand or convenience premium versus the leaders. The score is a normalised measure of grams of protein per dollar versus the rest of the catalog.
Within the Mass Gainer category specifically, this product ranks #14 of 14 (top 100%) by value. The category average Value Score is 18, so this product is below the typical mass gainer on cost-per-gram efficiency.
Best use case: For hard gainers and bulks - calorie-dense, carb-loaded shakes designed to push surplus calories with quality protein attached.
When to consider alternatives: If you are eating enough whole-food calories already, a plain whey blend is more flexible and cheaper per gram of protein. The related products below are ranked the same way and let you compare side-by-side.
