What this report establishes
The results above describe the sample of lot TZ-2510-A that Freedom Diagnostics analyzed (received Oct 28, 2026, reported Nov 1, 2026). Identity was confirmed by mass spectrometry and purity by HPLC with UV detection. This report does not include an endotoxin test. It does not describe other lots or strengths, and it does not establish any attribute the report does not list. Confirm that the lot printed on a vial label matches TZ-2510-A before applying this record to it.
How to read this report
Open the PDF and read it in this order. First the header: client, accession number (2610284030), search code, dates and lot (TZ-2510-A), which must match this page and the vial label. Second the analytical results: identity by LC-MS, purity by HPLC-UV and net content. Last the chromatogram and the mass-confirmation spectra, where a shoulder or a secondary peak tells you more than the percentage does. Guides: how to read a certificate of analysis, HPLC vs mass spectrometry, why the label weight is not the peptide weight.
Common questions about this report
- What does the 99.83% figure on this report mean?
- It is the main peak's share of the total detected peak area in the HPLC-UV run Freedom Diagnostics reported on Nov 1, 2026. It is a chromatographic purity result for that sample of lot TZ-2510-A; it is not a claim about other lots, and it is not a weight or net-content figure.
- How was identity confirmed?
- By LC-MS: HPLC with UV detection coupled with mass spectrometry. The PDF shows the chromatogram and the mass-confirmation spectra for Tirzepatide.
- How do I know the PDF is genuine?
- Enter search code Arct2610284030 on Freedom Diagnostics's certificate lookup page. The lookup is hosted by the laboratory, not by this site, which is what makes the check independent.
- Does this report apply to the vial I received?
- Only if the lot number printed on your vial label is TZ-2510-A. A different lot has a different report; if your lot is not listed on this site, ask support with the lot number.
