Independent Quality Data — Aggregated

CheckPept is an information platform. We aggregate publicly available lab results from independent testing services like Janoshik and Finnrick — we do not conduct tests ourselves.

How We Collect Data

We collect and aggregate publicly available test results from independent third-party laboratories such as Janoshik Analytik. Suppliers voluntarily submit their products for testing. We display these results transparently so you can compare quality across suppliers — we do not purchase or test products ourselves.
