BiOptimizers Subscription Policy

For every product on our site, BiOptimizers offers a one-time payment option and a subscription option. The latter allows you to subscribe to receive monthly orders of a particular product(s) at a lower price.

It should be noted that all subscriptions will begin on the date of the first subscription purchase made. Orders for the subsequent months will be automatically processed on the same calendar day of the month.

To cancel your subscription, you can contact our help desk at (800) 719-2467 Mon - Fri 10 AM to 8 PM EST or via email at [email protected].

BiOptimizers will accept a return of unopened bottles of the product(s) within 365 days of purchase. If you have purchased multiple bottles, in order to qualify for a full refund (excluding any shipping and handling charges), you will need to return all but one of the bottles unopened. The first bottle of the first purchase of any product will constitute a trial of the product (excluding instances where there has been an update to the product in which case it will be a different version e.g. MassZymes 1.0 vs MassZymes 3.0). Any return afterward with used bottles will attract a prorated refund.

Products are provided with a 100% satisfaction guarantee. You may contact our help desk within 365 days of the original order date for a 100% refund of the product purchase price (excluding any shipping and handling charges) and obtain an RMA (Return Mailing Authorization) number and shipping instructions to return any unopened product. RMA's are only available to customers returning items within the 48 contiguous United States, Alaska, and Hawaii.
