This page summarizes how that guarantee generally works; always confirm the exact current terms with the seller at checkout before purchasing.
PrimeBiomeThe advertised guarantee period begins on the date of purchase. Requests made after the stated window may not be eligible, so review your order confirmation date before requesting a refund.
PrimeBiomeRefund eligibility can depend on factors such as whether bottles are opened, whether shipping fees are refundable, and whether a return of physical product is required. Confirm these specifics on the seller's current written policy at checkout.
