Shipping costs on international orders cannot be reimbursed. All returns must be received in our office no later than 75 days from the date of original purchase to qualify for a refund. Allow 7-10 days for refund to appear on your credit card. Cancelled, or requests to return Autoshipments after shipping must be received in full in order to receive a refund. For example, when a customer calls and cancels an Autoship after it has been shipped and/or processed, then all bottles must be returned in original condition.

IMPORTANT: Returns without an RMA number marked on the return package will not be processed. We are not responsible for product sent back without authorization. Please include packing slip or a note including your original order number, name, address, and phone number. Please use the original packaging (if possible) and completely remove or cover the original shipping label. Seal the package securely with tape. Print our return address clearly on the outside of your package. Send your return package back using standard priority mail. Keep a copy of your original shipping receipt until the credit for your return appears on your credit card statement. We are not responsible if your shipment is lost in return transit. Purchases will only be credited to the account used to make the purchase. It takes approximately 2-3 weeks for us to receive and process your return. We’ll credit or refund the value of the item and any taxes you were charged (excluding delivery charges). Adjustments to credit cards should appear within two billing cycles. No refunds on/or multiple refund requests – for example, a customer orders and receives a refund on returning product and then re-orders and requests another refund. Only one refund per customer.
