FlowStrong is backed by a 60-Day Satisfaction Promise.
A refund requires prior authorization in the form of a Return Merchandise Authorization (RMA), requested by emailing support with the subject line “Refund Request - Order #_____.” Once issued, all bottles from the order (empty, unopened, or partially used), along with any bonus items, must be shipped back within 7 calendar days of receiving the RMA, using a trackable shipping method. Return shipping is the buyer's responsibility unless the wrong or a damaged item was sent.
Approved refunds are subject to a return-processing fee described by the brand as up to 20% of the order value, and original shipping and handling charges are non-refundable. Refunds are issued to the original payment method: 3 to 5 business days for inspection and approval after the return arrives, then 5 to 7 business days for credit card refunds or 5 to 10 business days for debit card refunds.
An alternative “Keep-the-Product Option” is also described: the brand may offer a partial refund without requiring the product back, at the company's discretion. Accepting it ends any further return rights on that order. One refund is permitted per product per household within any 12-month period.
Contact FlowStrong support directly with your order number to request an RMA before shipping anything back. Unauthorized returns are not accepted, per the brand's stated process.
