Help clinical research by telling your friends and family about ACS and receive a bonus payment.

Receive a $50 voucher for each eligible friend who completes a study.

To receive the Refer a Friend bonus:

  • Your friend must be new to ACS (not on our database)
  • Your friend must tell us during phone screening that they were referred by you
  • Your friend must complete a study for you to receive the bonus.
  • This bonus is intended for healthy volunteer studies only

You may not advertise or make any general solicitations for individuals to participate in a study. Eligibility for a Refer A Friend payment and payment amount will be determined by ACS. ACS at its discretion may change, amend, modify or terminate this referral program at any time without notice.
