Gelagen is sold with a 60-day money-back guarantee from your purchase date. The brand's own FAQ requests at least 30 days of use before requesting a refund if you are not satisfied.
Contact Gelagen's official customer support directly — not this website — with your order number, within the guarantee window confirmed at your time of purchase.
Since the brand frames the fullest results as building over months, calendar your refund deadline as soon as your order arrives.
