Late last year Universal Nutrition dropped their gift to the slow release protein market, Casein Pro. Originally the supplement was previewed in two flavors, chocolate milkshake and vanilla soft serve, with one 2lb size. Over it’s existence the product has had it’s range increased with one more taste, cookies and cream, and one extra volume, 4lb. Despite already having more options than most, Universal have headed back into the kitchen, and come out with a fourth flavor for Casein Pro. Joining the supplement’s cliché menu is easily the most creative variant of the bunch, chocolate peanut butter banana. The unique new taste has been produced for both size options 2 and 4lb, and should be showing up in retailers soon as it’s already available direct from Universal Nutrition.
