Study Participant FAQs

Your participation is 100% virtual. We ship the product directly to your home, and you share information about your health and your behaviors through our online surveys. All your information is kept strictly confidential.

To be the first to know about enrollment and sign up for future studies, please subscribe to our newsletter here. We’ll reach out when we begin recruitment. You’ll then be asked a few screening questions to see if you qualify. Thanks for your interest in helping us gather data on health and wellness products!

Radicle studies are short and most of them last about 4-6 weeks! We ask you to take your study product as directed during the study and answer the surveys that we send to you through email or text message. We’ll send you a final and feedback survey to take at the end. It’s so easy!

You will receive a Personalized Participant Report which provides insights based on your study responses and tells you how you did, along with the product for the study at no cost to you.

Of course! You can always share information about the study with your primary doctor or healthcare provider. You can continue to see your doctor throughout the study for routine visits and tests.

Our core focus is gathering clinical data to validate health and wellness products, the first of its kind! Our virtual, direct-to-consumer studies enable a smooth experience for participants, as well as enabling us to bring much needed equity and diversity into medical research. The unprecedented scale and reach of our studies finally enables inclusion of diverse ethnicities, genders, age groups, behavioral habits, and pre-existing health conditions to move us closer to personalized medicine for the population at large.

And unlike most studies, we share your results with you after the study in the form of a Personalized Participant Report, which not only summarizes your usage patterns over the course of the four-week study, but also compares your individual data to both the study population and relevant demographics and/or behavioral subsegments for actionable insights.
