While it may have only just been unveiled this past weekend at the Arnold, the all new protein powder Performix Pro Whey is already available. As always GNC is first to launch the latest from the brand, making the supplement available in both of its 2 and 4lb sizes, as well as its three flavors, Chocolate, Vanilla and Cookies & Cream. The prices on Performix Pro Whey, which is something a lot of people have been asking about are $34.99 and $69.99 for Gold Card members, and $44.99 and $79.99 for everyone else. There are no deals available on either size at the moment, although we wouldn’t be surprised if got one in the near future.
