Nutrition, ingredients, and allergens read from the brand's official Chocolate Fudge nutrition panel image. The ingredients list 'Natural and Artificial Flavors'. Informed Choice certification is claimed on the brand page and was not cross-checked on the certifier's site. The brand states '6g+ BCAAs', which is not an exact figure, so bcaa_g is null. Prices are brand-site Chocolate Fudge prices: $44.99 (1.5 lb) to $134.99 (5 lb), 2026-10-13. Servings per container, country, and retailers were not verified. The brand site also lists separate products (Naturally Flavored R1 Protein, Clear Whey Isolate, Whey Protein, Source 7, Plant Protein); those are not covered here.
