What We Do

Verification you can verify

01
🔬

Third-party lab

All testing through Janoshik — an accredited, independent analytical lab with no affiliation to any manufacturer or seller.

02
🔒

Members only

Results are never public. Only contributors who funded a test see the full data. Access is permanent as long as your account is active.

03
🤝

Community-funded

By pooling costs across contributors, each person pays a fraction of what an individual test would cost. Strength in numbers.
