Research notes
This is Rule 1's three-whey blend (concentrate, isolate, hydrolyzed isolate), not R1 Protein Whey Isolate. Price is Amazon's current one-time price (ships from Amazon, sold by Rule One Proteins, no deal badge, no Typical price shown). The brand's own store listed the 5 lb tub at $109.99. Nutrition is from the brand's Chocolate Fudge Nutrition Facts panel, which doesn't state servings per container; the 65 servings come from the Amazon listing title and its label image ('65 servings per container'). Amazon's rating count is shared across sizes.
