99.1% mean measured purity across 381 positive purity tests; 4 below 90%. The 90% grouping is not a safety threshold. 7 additional tests did not detect the expected compound.

How many QLP lab test records has TitrateLab tracked?

TitrateLab has 391 lab test records for QLP. Tested from 2025-05-15 to 2026-10-27. A test record is not necessarily a unique certificate.

How do QLP's measured fills compare with the label?

Last 6 months: no comparable fill test. All time: 10 of 22 fill tests within ±15% of label, 5 more than 15% under and 7 more than 15% over. The measured amount is compared with the printed label. Finnrick quantity comparisons are excluded because they use a vendor batch claim. Missing tests are not passes.

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.

391 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 19 records have a classifiable result. Community sentiment describes reviews, not laboratory measurements or independently verified purchases. Results are not certification, medical advice or endorsement.
