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.
3 of 7 present · 3 passed · 0 failed · 0 reported · 4 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).
GLP TZ confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.784%
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
Tested · passed · core
LAL or chromogenic endotoxin assay.
Replicate 1: Pass, Replicate 2: Pass
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
99.784% purity by HPLC-MS is excellent and typical for research-grade peptides

Mass spectrometry shows expected molecular ion peaks for tirzepatide with proper charge states
Batch number present
Lot GT10-032026-1 clearly documented
Dates documented
Received 2026-03-10, Reported 2026-03-11 - reasonable turnaround
Lab verification needed
Freedom Diagnostics claims USA operation with verification URL, but independent verification of lab accreditation/credentials recommended
Limited testing scope
Only identity, purity, and endotoxin panels present. Missing heavy metals, microbial, sterility, and residual solvent testing
Research-only disclaimer
Document includes standard research-only disclaimer stating not approved for human/veterinary/diagnostic/therapeutic use
