Product authentication tips
We know that quality is as important to you as it is to us. Use the tips on this page to help authenticate original Optimum Nutrition made products.
NECK BANDS AND STICKERS REMOVAL
As part of our continued sustainability effort, we are removing the black plastic neck band and gold hologram from tubs of Gold Standard 100% Whey. This is a transition process so you may receive a tub with or without the neck band depending on where or when you purchase.
Other products that have black, silver or clear plastic neck bands will also be removed in the future.
TUB DESIGN
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.
DATE & BATCH CODES
On the bottom or side of protein tubs you’ll find 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.
