Tirzepatide Certificate of Analysis Results
What the Tirzepatide record shows
Evidence through 2026-09-02TitrateLab tracks 10,065 published Tirzepatide certificate-of-analysis records through 2026-09-02. Across 10,061 records with a usable peptide-purity result, the median reported purity is 99.8%. Across 8,615 records with measured-versus-label dose data, 55% are within 10% of the labeled quantity. This is a public convenience sample, not a randomized market survey; one result describes one submitted sample and does not verify other batches.
Limits and missing evidence
- The testing laboratory is unattributed on 42 records.
- Coverage depends on reports that were published and available to ingest.
