Cancelling Your Order

  • If you would like to return an item please contact us on 0345 688 5120, email [email protected]. We will provide you with a return authorisation which will speed up your return and refund process. You should then send us the goods in their original condition and packaging to the address in the "Contact Us" at section 2 above marked "Returns". We reserve the right to refuse returns or to charge you our fees and expenses if the product is received otherwise than in accordance with this requirement.

  • We recommend that you insure the return shipment as you are under a duty to take reasonable care of the goods and will be liable for damage to them until we receive them at our warehouse. We also recommend that you use a secure, trackable means to return your order to us at Optimum Nutrition, Unit 1-3 Orion Park, Orion Way, Crewe, Cheshire, CW1 6NG and that you retain proof of sending, in case of a dispute.     

Please note that you are responsible for the cost of the return shipment.

All items must be returned unused, in their original condition.

We will refund the price of the product in full, including shipping costs, within fourteen days of receiving your notice of contract cancellation, provided the goods are returned within that period.

  • If you wish to exchange a product or flavour, please contact Customer Services within 14 days or receiving your order so that your account can be updated. Before returning the item, please either email [email protected] or write to us at: Optimum Nutrition, Unit 1-3 Orion Park, Orion Way, Crewe, Cheshire, CW1 6NG.

  • There is no charge to exchange items for a new flavour or different size, however all exchanges are based on stock availability. Shipping is also free on the replacement item.

  • Goods are classified as faulty if they are received damaged, or where a manufacturing fault occurs within six months of purchase. Please note that items that are damaged as a result of wear and tear are not considered to be faulty.

We will usually process the refund due within 14 days of the refund notification email, including a refund of the delivery charges for sending the item to you and the cost incurred by you in returning the item to us. We will refund any money received from you using the same method originally used by you to pay for your purchase.
