Sources, definitions & limits

Names on reports; vendor role unverified. A test record is not necessarily a unique certificate.

The reports describe the batches that were tested, not an untested vial or an offer from this vendor.

356 published records are attributed to this vendor. The current certificate index excludes 0 repeated records using file hashes and supported lab verification links. Missing identity keys can leave repeated certificates. Recorded name groups can include variants, mixtures and unclassified names.

Evidence dates describe the tested samples, not when the vendor was founded, current stock, or a performance trend. Purity uses positive measurements only. Exact-zero purity is a not-detected identity outcome, not proof of an empty vial. A zero measured amount requires an explicit numeric amount result; missing amounts are not zero.

Underfills and overfills here exceed 15% in either direction against the printed amount. Vendor batch claims are not used; Finnrick quantity comparisons are excluded. Recent outcomes cover 2026-05-01 through 2026-11-01, inclusive. The summary, charts and FAQ use these same definitions. Missing tests are not passing results.

Endotoxin failures, borderline outcomes and passes use the recorded lab verdict. A pass is not proof of no endotoxin. Only 25 records have a classifiable result. Community sentiment describes reviews, not laboratory measurements or independently verified purchases. Results are not certification, medical advice or endorsement.
