Thank you for ordering at Optimum Nutrition! You will receive an order confirmation email once the package has been dispatched. This will usually be sent the same day as you order. It is possible that the confirmation ends up in the spam box of your email. Therefore, always check your unwanted inbox or spam.

Can I cancel or modify my order?
Unfortunately, it is not possible to modify or cancel your order once it has been placed.
As soon as your order is completed, it is immediately processed in our warehouse to ensure the fastest possible shipping. This means we can no longer stop the cancellation.

If you do not wish to receive the order, you have two options:

• Refuse the package upon delivery – Inform our customer service that you are refusing the order to avoid any additional costs. DPD will then automatically return the package to us.

• Request a free return label – Once you have received the package, you can contact our customer service or create a ticket here to request a free return label in accordance with our return policy.
