Short answer: ProstaStream offers a 90-day money-back guarantee from the date of purchase. Return unused or empty bottles within this timeframe for a full refund — no restocking fees, processed within 7–10 business days.
Why "no restocking fees" is a genuinely reassuring policy detail
Some return policies deduct a restocking fee from your refund — explicitly ruling this out removes a common source of customer frustration.
What the guarantee process specifically involves
Return unused or empty bottles within this timeframe — a specific, direct process, with refunds processed within 7–10 business days once your return is received.
💡 Worth knowing: confirm the exact current terms and return address directly with customer support before initiating a return.
