What our study participants are saying

  • Testimonial #1

    I recently participated in a ProSciento study and was very pleased by their level of professionalism, the attentiveness of the staff, and the quality of the facility. Everything was clearly explained and the study advanced as expected. It will be cool to learn in the future how many people’s lives were improved by the result of this study, hopefully, many thousands.

  • Testimonial #2

    Great experience with this company, you won’t find a better opportunity to help people.

  • Testimonial #3

    Participating in a clinical trial was a life changing experience for me, understanding how trials are conducted to develop new medicines. To be part of this was an eye-opening experience. The knowledge I gained about my health is invaluable. Their dedicated staff is admirable, and everyone was super friendly. I would like to participate in future trials at ProSciento.

    For your safety, study participants must remain on site during inhouse stays when participating in a study. We offer twice-daily walks and entertainment options during your visit.

  • Do you have other locations for screening visits or clinical studies?

    Generally, all screenings and study visits will take place at our Chula Vista facility. We may ask you to get some lab work and procedures done at other off-site locations, but this varies largely on the study. Our study participant recruiters can provide you with more information during your call.
