**Product Packaging Information
Please note due to Covid challenges, we have faced supply chain constraints sourcing packaging components for our products. As a result, packaging cap and bottle colors may vary, temporarily, across some of our products. Despite these challenges, we are here to help you stay stocked with your favorite Optimum Nutrition products to support your fitness goals. Rest assured that these variances affect packaging only, it does not affect the product inside. We are still delivering the same high quality products backed by 30 years of the highest quality standards. Thank you for your understanding during this time.
