While Athletic Xtreme’s new Gym Juice has only just started making its way into stores, hitting places such as Nutraplanet, it turns out the brand have already decided to add another flavor to the supplement’s menu. Since Gym Juice was first previewed, there was just the one flavor we were told about and had seen in promotional pictures. The one option we knew the latest from Athletic Xtreme was going to be coming in was watermelon, a classic pre, intra and post-workout taste. Joining the one and only Gym Juice flavor will be yet another classic fruity recipe, with green apple taking the product to a total of two. Athletic Xtreme haven’t gone into too much detail about when fans will be seeing green apple Gym Juice on shelves. On the bright side however, they have said it’s available now suggesting stores are being given the choice to stock it.
