From NutraBio:
"Two decades ago, NutraBio launched a protein powder that was so simple and honest it makes you wonder why it took the industry so long to catch on. Each serving of our Classic Why contains 25 grams of complete protein derived solely from highest grade of whey protein concentrate known as WPC80. NutraBio Classic Whey has never been nitrogen spiked and contains only WPC80 with NO inferior ingredients like WPC34, sweet whey, dairy creamer, maltodextrin, dextrose, or other fillers."
