Earlier this week Pro Supps announced a new flavor for its isolate protein powder PS Isolate. The addition introduced was Cookies and Cream, which is due to join the product’s other three flavors on shelves next month. Only a handful of days later Pro Supps has now announced yet another new option for PS Isolate. Following on from Cookies and Cream the brand has unveiled the supplement’s fifth flavor with Peanut Butter Cookie PS Isolate. Just like Cookies and Cream, Peanut Butter Cookie will be added to the isolate protein’s menu sometime next month, with Pro Supps’ website expected to be the first place to get it.
