We offer a full refund on the purchase price of any of our exclusive formulas (minus shipping) any time within 60 days of your purchase. We do not require the return of unused product for a refund on the first bottle of any formula purchased. However, for fraud protection, we require the return of product for any refunds beyond the first bottle. This guarantee valid for all LEGION™ formulas, with the exception of WHEY+, which is required to be returned to qualify for a refund.
