Sources

Nutrition (Triple Chocolate, 47 g scoop), ingredients, sweetener, allergens, flavors, 1.8 lb size, $28.99 sale price and 18 servings from the official sixstarpro.com product page (2026-10-13). Brand page panels for Triple Chocolate/Vanilla Cream say 'Approx. 40 servings', which conflicts with the 18-serving header for the 1.8 lb tub; 18 used. BCAA 6.6 g is a brand marketing claim. Brand claims 'Banned-Substance Tested' / 'Safe Choice' without naming a certifier, so no certification listed. Ingredients list 'Natural and Artificial Flavors' and 'Soy and/or Sunflower Lecithin'. Kellogg's flavor editions confirmed via grocery retailer listings only.
