What Is It: Gainers these days are all about quantity, but what about the quality? It took Cellucor 3 years to come out with this gainer, and they did it the right whey. The understand that everyone is different but they also knew that it takes calories in carbs and protein to gain mass. In Cor Performance Gainer, they gave the consumer the choice how to take their Mass Gainer with their "dial up and dial down" formula, By offering a whopping 56 scoops per bag, you can take just one and deliver 300+ calories with 30g of protein or dial it up if you need more. Its pretty revolutionary, but something you would completely expect with Cellucor.
