Contact the research site through the registry page, complete a short phone screen, then attend an in-person screening visit.

Frequently asked questions

Are clinical trials in Surprise safe?
Every trial on this page is registered on ClinicalTrials.gov, the official NIH registry, and is overseen by an Institutional Review Board (IRB). Before joining you receive an informed consent document detailing procedures, risks and compensation. Participation is voluntary and you can withdraw at any time.
How do I join a study in Surprise, AZ?
Pick a study that matches your profile, contact the research site (or apply through the study links on this page), pass a phone pre-screen, then attend an in-person screening visit. If you qualify, you review and sign the informed consent and the study begins. The process typically takes 1-3 weeks.
What is the difference between a research center and a hospital study in Surprise?
Dedicated research centers (listed on this page with their Google ratings) run studies as their core business — often healthy-volunteer and vaccine studies with structured compensation. Hospital and university studies tend to focus on patients with specific conditions. Both types are registered and IRB-supervised.
How often do new paid studies open in Surprise?
Constantly — trials open and close enrollment every week. This page is refreshed weekly from the NIH registry. Join the email alert to be notified when a new study opens within 30 miles of Surprise.
Can I be in more than one clinical trial at a time?
Generally no — most studies exclude participants currently enrolled in another trial, and paid Phase 1 studies enforce a washout period (often 30 days or more) between studies. Frequent healthy volunteers in Surprise typically complete one or two studies per year.
