HorseFil is backed by a stated 60-day money-back guarantee from the date of purchase. Based on available information, the typical process is to email customer support with "Refund Request" in the subject line and mail back all bottles from your order (opened or unopened) to the designated return address. Refunds are reported to process within 5–10 business days of receipt, and return shipping costs are generally the customer's responsibility.
Important: independent coverage has noted this guarantee window described inconsistently across different pages of the brand's own website. We recommend confirming the exact, current, binding terms on the official order page or your order confirmation email before purchasing.
