7-panel checklist
Had data + good, had data + bad, reported without pass/fail, or missing. Missing lowers thoroughness — you decide whether that panel matters; PeptIQ’s score still factors coverage.
2 of 7 present · 2 passed · 0 failed · 0 reported · 5 missing
Missing is a thoroughness gap — not automatically bad. PeptIQ’s legitimacy score still weighs panel coverage; you can down-weight panels that don’t matter for your use case.
Identity
Tested · passed · core
Compound identity confirmed (e.g. HPLC, mass spec).
ID Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
>99.9%
Heavy metals
Not on this COA
Lead, arsenic, cadmium, mercury, or similar limits.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Microbial
Not on this COA
Bioburden / microbial limits testing.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Endotoxin
Not on this COA · core
LAL or chromogenic endotoxin assay.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Sterility
Not on this COA
Sterility testing where applicable.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Residual solvent / water
Not on this COA
Residual solvents or water content limits.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
How to read this
Had data · good
Panel present with a pass (or clear acceptance).
Had data · bad
Panel present with a fail — a concrete quality signal.
Had data · unclear
Value reported without an explicit pass/fail mark.
Missing
Not on this certificate. Lowers thoroughness; you decide if that panel matters for your use case. PeptIQ’s score still factors coverage.
Findings
Evidence-linked observations from this audit.
High purity confirmed
Chromatographic purity >99.9% with 99.9% of label claim (39.9 mg of 40 mg) is excellent and typical for research-grade peptides.
Identity confirmed by mass spectrometry
Mass spectral match confirmed via HPLC-UV-MS with reference spectrum shown on page 2. CAS number 2023788-19-2 matches Tirzepatide.
Batch/lot number present
Batch/Lot qrgqb8d clearly stated with vial photos showing matching label.
Dates are valid and consistent
Sample received 3/18/2026, testing completed and report issued 3/22/2026. Both dates are on or before today (2026-07-29) and show reasonable turnaround time.

Limited testing panels
Only identity and purity panels show results. Methods for endotoxins and heavy metals are described on page 3 but no results are reported. This is not uncommon for basic peptide COAs but limits safety assurance.
Professional presentation
Document includes chromatogram (page 2), mass spectrum comparison, detailed methods summary (page 3), and proper header/footer with lab contact information and copyright notice.
