“I’ve been volunteering at Biotrial for their clinical studies for 4 years now. That’s my secret for traveling the world. The staff really takes care of us and strives to make us feel comfortable throughout the trial. I’m a regular volunteer and have no plans of stopping anytime soon.”

Mateo, 25, Student

“I decided to volunteer for clinical trials because I needed extra income to go back to school. I was nervous at first, but the people were very knowledgeable of procedures and made me feel that my safety is a top priority. I will recommend this to friends who want to earn extra money. When one of my friends participates I will get a referral bonus from Biotrial!”

“My poor sister suffered from osteoporosis since she was in her 20s. I never had any health issues and when Biotrial opened the registration for a medication to treat osteoporosis, I didn’t think twice about joining. I took a week’s vacation and did the study. I am proud to help other people from going through the pain that my sister experiences with osteoporosis.”

“Soon after I retired, I became a widow. I wanted to do something good for others. And I thought, why not join clinical trials? It may not seem like a big deal, but this is my way of making a difference.”

Why Volunteer

Medical heroes are everyday people who help advance public health and medicine by volunteering in clinical trials.

Referring a friend is a good way to help advance medical research and earn money when your friend participates in a clinical trial. The more friends you recommend, the better your chance of earning.

Our Refer a friend program only applies to medical studies with in-house stays. Referees must be first-time participants or registered volunteers who did not participate in  clinical trial at Biotrial in the last five years.

You do not have to participate in a study to earn money when you refer a friend.
