Customer Care


Cancelling Your Order

  • If you would like to return an item please contact us on 0345 688 5120, email or fill in and return to us this form. 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, Lodge Road, Sandbach, Cheshire. CW11 3HD 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.
