Offering Only The Best! Since 1990, the Jay Robb Corporation has been producing what we feel are the best-tasting protein powders on the planet. To the best of our knowledge, we were the first company in the world to create a whey protein powder made from cows not treated with rBGH (a synthetic growth hormone). Because rBGH-free whey is primarily obtained from small farms throughout the world, there is only a limited supply. The Jay Robb Corporation secures large quantities abroad each year to meet our growing needs; however, there are times when the world supply runs short. During these periods, we may choose to procure the highest quality domestic whey protein in conjunction with rBGH-free raw materials to produce our world-class whey protein. -JayClinical NutritionistCreator of the JayClub Discover my secrets for staying lean for life by joining JayClub.
