The 90-Day Guarantee: Opened And Unopened Bottles, Explained

This formula's own materials state something worth highlighting on its own: the guarantee covers both opened and unopened bottles.

What this specific detail actually means

Prosta Defend offers a 90-day money-back guarantee that covers opened and unopened bottles — a real, meaningful difference from a guarantee requiring unused product.

What to actually confirm before ordering

Refunds are typically processed within 5-7 business days after return confirmation, per the brand's own materials — worth confirming the exact return process directly before you need it.
