Do you want to be paid up to $350 per day for your time?

We’re looking for healthy people to participate in clinical studies of new medications. All visits occur at Nucleus Network’s specialized clinic located in the heart of the Minneapolis-St. Paul metropolitan area. Due to COVID-19 restrictions, we currently only allow participants who live within 300 miles of our clinic. 

  • There is a wide variety of start dates and study schedules
  • While you are in our comfortable clinic we provided free catered food and high-speed WiFi
  • We are testing treatments for medical conditions that affect millions of people around the world - you can have a real impact

You can combine taking part in a clinical trial with studying or working online from our clinic - or you can just watch Netflix and play video games.


By taking part you help to advance medicine and improve lives.
