The evidence behind the label

Tirzepatidelab reports.

Identity, purity and amount are different questions.
See what was measured—and where the evidence stops.

10,920 published results · 10,680 report groups · 5 duplicate records consolidated How we count ↗

TitrateLab indexes 10,920 published Tirzepatide laboratory results from 10,925 source records, after consolidating 5 duplicate records. 92 results record an identity failure; 1 additional identity concerns need review. Median measured purity is 99.84% across 10,161 applicable results. 53.6% of 6,391 comparable label-amount results are within ±10%. The latest recorded test date is 2026-09-06. Purity statistics exclude identity failures, identity concerns and zero results; adverse outcomes remain counted separately. TitrateLab did not perform the laboratory tests. Published samples are not a random market survey; one result does not verify other batches.

How these histories are selected and ordered

This comparison uses a narrower population of reviewed vendor identities and source-linked reports. Duplicate and attribution checks run before selection. The existing evidence-weighted order favors repeated results without a recorded identity concern, then measured purity and report count. Positive purity is not an explicit identity confirmation; unclassified reports are not counted as clean observations. A concern in extracted notes may need source review. Domestic refers to U.S.-based resale, not U.S. manufacture.

04 / Sources & method

Know what the numbers cover.

Published reports describe submitted samples. They are a convenience sample, not a randomized survey of the market or a guarantee about another vial.

Report a correction →
Records, results and reports

10,925 published source records become 10,920 results after 5 duplicate records are consolidated. They form 10,680 report groups using shared report references and file hashes. Records without a proven shared reference remain separate. A report may contain more than one result; conflicting measurements remain visible. These are not counts of unique batches or vials.

Identity and missing evidence

92 results record failed identity or an absent compound. 3 explicitly confirm identity in the extracted record. 10,824 have no explicit verdict; their original reports may contain information not yet extracted. 1 additional concerns need source review. Missing evidence never becomes a confirmed identity result.

Dates, freshness and coverage

Included test dates run from 2022-07-28 to 2026-09-06. 176 results have no usable test date. Aggregate calculated 2026-09-08T08:16:56.343792+00:00; this is not a test date. This summary refreshes every 10 minutes; new report groups depend on ingestion. The research overview counts raw exact-token source records, while this archive normalizes compound names and consolidates matching result signatures; those totals need not agree. Monthly counts use test dates only.

Definitions and source provenance

Purity below 97% is a browsing threshold, not an overall quality grade. Amount categories use the same ±10% boundaries and exclude absent-compound sentinels, noncomparable values and batch-claim deviations. Endotoxin classifications use explicit report verdicts and recognized stored outcomes; numerical readings alone do not establish a pass or fail.
