"Refer A Friend" Program

What is it? How does it work?

Tell your friends and family about our studies. They make a screening appointment online at or call the recruitment department at 210-225-5437.

They then come in for a screening and fill out a referral form at the screening appointment naming you as the person who referred them. Forms cannot be filled out at a later date or filled out for people who screened before the program was started for that study.

*The amount paid out is stated on the form when it is filled out.  If the amount paid for a study is later increased, a new form is created with the start date for that amount. People who previously filled out the form, will not be paid the new amount. 


If they pass screening, dose and complete the study  -->   You get an gift card! (A variety of choices available)


See individual studies for specific criteria for that study's Refer A Friend details.
