RivalUs has announced an all-new flavor that it’s actually added to two of its supplements. Both of the products getting the option are protein powders with the brand’s longtime formula Promasil, and its more recently released Rival Whey. The two supplements do already have quite the list of flavors, however they now have even more to choose from thanks to the RivalUs addition of Banana Creme. The brand has immediately added its latest effort to its website, where it can be purchased in 2 and 5lb tubs for both Promasil and Rival Whey, although not the former’s 1lb or the latter’s 10lb.
