Your milk can answer questions
no one else can

Little is known about how medications transfer into breast milk. We've spent decades building the evidence base — and every sample donated by a breastfeeding mother moves the science forward for the next one.

How to participate
Step 1
Check eligibility

Currently breastfeeding and taking one of the medications we're studying? You may qualify to contribute.

Step 2
Donate a milk sample

We send you a collection kit and walk you through the process. Prepaid overnight shipping is provided — most participants donate once across a feed cycle.

Step 3
Help future mothers

Your sample becomes published evidence that pharmacists, OBs, and mothers rely on when there are no other answers.
