Prostadine carries a 60-day money-back guarantee from the date your order is delivered.
The guarantee runs for 60 days from delivery and covers dissatisfaction with your results or your overall experience. That window comfortably covers the 8 to 12 weeks nutritional support of this kind typically needs to show an effect.
Contact the official store directly with your order number, within the 60-day window. Customers are generally asked to return purchased bottles to the company's warehouse for the refund to be processed; confirm the exact steps with support before shipping anything back.
