In our original post outlining details of Optimum Nutrition’s Pro Series Pro BCAA. We mentioned that the supplement would be coming in a total of three tastes, fruit punch, raspberry lemonade and the convenient unflavored. It turns out the maker’s of Gold Standard have produced an exclusive flavor for the store that rates their flagship protein powder #1, Bodybuilding.com. Arguably the most popular supplement store on the internet are currently listing a fourth Pro BCAA beside the promised three, with a third fruity flavor peach mango. There is of course no extra charge for the Bodybuilding.com only option. However if you purchase Pro BCAA in any flavor while stocks last, you will score yourself a three serving tub of Optimum’s Gold Standard.
