ProstaMaster is generally sold with a money-back guarantee window through the official store.
Guarantee length, eligibility and the return process for supplements in this category can vary by promotion and are set by the merchant, not by this website. We strongly recommend reviewing the current guarantee terms on the official order page before completing your purchase.
Contact the official store directly with your order number. Some guarantee programmes require unused or empty bottles to be returned; confirm what applies to your order before shipping anything back.
