With our exclusive ON shaker cups, mixing-up even the largest and thickest protein or meal replacement shake is a snap. Each shaker cup has an Extra-Large 32 fl oz capacity and a 3 ¼” opening at the top that makes adding full-size ice cubes a simple proposition. Last, but certainly not least, we’re proud to say that our shaker is BPA-free and made in the USA.
At ON we are proud to know that we are one of the few sports nutrition companies who own and operate their own production facilities. While it's true that ON is one of the world's largest producers of sports nutrition products, we remain focused on being recognized as the best. In fact, our requirements for raw materials are so strenuous that it's not unusual for ON Quality Assurance Technicians to reject entire truckloads of raw materials that do not meet our high standards. We like to think that we take as much pride & care in crafting our award-winning supplements as our consumers do with crafting their physiques and fitness accomplishments.
THERE IS ONLY ONE GOLD STANDARD
