Herbal Ultra return policy follows industry standards. We offer a refund on unopened bottles received within 30 days of the order. There is a 20% restocking fee to cover commissions, shipping charges and handling. Please remember that a healthy diet & exercise regime is the first step to any health solution. Genetics also play a major role in how any medicine or supplement will work for you. Thus it is impossible to know the exact results with any one individual. Best in health.
