All customers who buy the product via the official website can use the 60-day money-back guarantee. To get into further detail, you can have all of your money returned to your bank account if you return your bottles 60-days after being shipped. The company will let you know when the product is shipped via email. Two things that you need to keep in mind are: the company does not cover return shipping costs, you must send back ALL the bottles, and the company will make sure your money is returned a couple of days after receiving the bottles.
