How to create a return


To qualify for a refund, we require the thin KOS label that surrounds the product bottle to be returned along with your original order # and the return authorization (RA) # assigned to your return. It is your obligation to pay the return postage, and we do recommend you opt for tracking and confirmation numbers for verification of delivery. We must receive the label(s) within 90 days from the date of original purchase for the refund to be valid.

If you need assistance with your return, you may also contact us at 1-844-586-4567 Monday through Friday between the hours of 9:00am and 5:00pm Pacific Time, or by emailing us at
