Your poop could save lives.

Welcome to Poop with Purpose, a stool donation program that’s committed to the safe collection of stool from healthy individuals. We see the potential in your stool—the healthy microbes that could be used to further research, develop promising new treatments and potentially cure serious medical conditions.

But we can’t do it without you.
As a stool donor, you could save lives and earn as much as $1,500 per month. Pooping has never been so rewarding.

Can you donate your stool? See what it takes

At a minimum, donors must:

Live in the Boston Area

Donate 3 times per week on site

Be 18-49 years old

Pass health screens & tests

Earn $50 per donation.

Why donate? You can doo good.

What if the microbes in your poop held the key to preventing recurrent C. difficile infection?  Or relief for children with autism who suffer from gastrointestinal symptoms? In short, what if your poop could make a difference in the lives of millions?

You’d think about pooping in a whole new way. Don’t flush a potential lifesaving cure down the toilet.

Sit down, get comfortable.

Your safety is our priority.

Our screening process and stool collection methods are safe and confidential. And with added safety protocols during the COVID-19 pandemic, you can donate with peace of mind.

Donating at our facility is easy.

We are conveniently located in Cambridge, between Central Square and Kendall Square, close to public transportation and free onsite parking. Once donors pass our screening process, you can do your business and go about your business in as little as 15 minutes. We’re open Monday through Thursday from 7:00 am until 5:00 pm.

We're professionals who care.

We recognize that people like you are essential to our mission of transforming lives. We appreciate your commitment, respect your time, and strive to make your experience as comfortable as possible.
