Amazon Orders

If you are experiencing issues with your Amazon.com order and have been directed to contact us (the manufacturer), please understand that only Amazon can provide a refund. It may be best to directly speak with an Amazon representative to facilitate such a request, rather than using their mobile or desktop application. We unfortunately do not have access to create refunds or reprocess orders placed on their site. 

C4, Cellucor and Xtend products shipped and sold by Amazon under the Cellucor Brand Store are not Seller managed, meaning that Amazon processes payments and ships product sold from one of their many fulfillment warehouses across the country.
