Participants receive compensation for their time and travel.  Since studies require different amounts of paperwork, appointments, and time, the amount of compensation is different for each study. Compensation usually takes the form of a MasterCard© Cash Card that can be used like a debit card. In some cases, movie passes (AMC & Regal) may be offered. Of course, all study services and supplies are free. You will be given details about compensation before you decide whether to participate in a study.

For many of our studies, you will receive compensation after each visit. For other studies, you will receive compensation at the end of your participation based on the number of visits completed and how many of the study procedures you completed.
