Documentation

Quality you can verify, not just trust

Every vial carries a lot code. Every lot code resolves to a signed third-party report you can read before you order.

Independent, not in-house

Testing is contracted to a U.S. analytical laboratory with no commercial interest in the result. We publish what comes back, including the batches that fail and never reach the store.

Lot-level traceability

The code printed on your vial - not the product, the lot - is the key to its report, its release date and its retained sample.

Released before listing

A batch is only listed once its report is filed. If a lot is still in testing, the SKU shows as pending rather than shipping on a promise.
