Since 1988, the Jay Robb Corporation has been producing what they feel are the best protein powders on the planet. To the best of their knowledge, they 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 rBHG-free whey is primarily obtained form small farms throughout the world, there is only a limited supply. The Jay Robb Corporation secures large quantities abroad each year to meet their growing needs; however, there are times when the world supply runs short. During these periods, they may choose to procure the highest quality domestic whey protein in conjunction with rBGH-free raw materials to produce their world-class whey protein.
