Tubs of Gold Standard 100% Whey have a gold hologram seal on the black plastic neck band. Platinum series products have a clear neck band with silver hologram. Other powdered products have either black or clear plastic neck bands without holograms.
The crease on the bottom of U.S. made tubs of protein is a mold mark from plastic thermoforming. It looks the same on every tub and is normal. Tubs produced in the U.K. have a circular indentation without a line running across the bottom. This is normal for European made tubs.
On the bottom of protein tubs you'll find blue ink jet printing listing a manufacture date, expiration date and batch code. Powdered products have a 2-year shelf life, so the dates should be 2 years apart. On bottles of capsules, tablets and softgels, the dates and batch code are printed on the side in white.
Under the cap of protein tubs is a cardboard vacuum barrier that helps hold powder in place during shipping. This round disk is not for sanitation and is not glued into place. It is common for the cardboard to stick under the cap. The round seal under the caps of bottles containing capsules, tablets and softgels is glued down and typically won't stick under the cap.
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.
