Gelagen is sold with a 60-day money-back guarantee from your purchase date, per the brand's stated terms.

The detail worth understanding before you order
A 30-day minimum use request: the brand's own FAQ asks that you use the product for at least 30 days before requesting a refund if you are not satisfied. That still leaves you a full 60 days from purchase to decide and request one.
How to request a refund
Contact Gelagen's official customer support directly — not this website — within the 60-day window from your purchase date. We were not able to independently test the refund process ourselves, so confirm current steps directly with support.

Calendar your deadline the day your order arrives. This is the single most practical thing you can do to protect your guarantee.
