I don't see BCAA in the ingredient list,
Ingredients:
Ultrafiltered Low Temperature Processed High Quality Instantized Whey Protein Concentrate (containing Micro Fractions) {Cow}, Cross Flow Microfiltered Undenatured Whey Protein Isolate (included Beta Lactoglobulin, Alpha Lactoalbumin) {Cow}, Natural and Artificial Flavors (Maltodextrin, Dextrose, Artificial Strawberry Flavors, Gum Arabic, Silicon Dioxide), Sucralose.
I see cows though, so they might have cut up some cow parts and put them in the tub. Hope you don't get any cow brains in yours.
