Clover is free for participants. Any site asking you for money is not a legitimate study.
You can always say no
Nothing is binding until you sign the informed-consent form with the study team, and even then you can withdraw.
Compensation is confirmed in writing
The amount on the listing is confirmed by the study site before you enroll, including the payment schedule.

Frequently asked questions
Straight answers to the things people ask us most.
A clinical trial is a research study that tests whether a new treatment, device, or approach to care is safe and effective in people. Trials are run by hospitals, universities and pharmaceutical companies, and every one on Clover has been reviewed and approved by an Institutional Review Board (IRB).
