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).
GLP TZ Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.58%
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
HPLC-UV purity of 99.58% with clear chromatogram showing single dominant peak at retention time ~15.0 min
Identity confirmed by LC-MS
Mass confirmation spectrum provided showing expected molecular ion peaks for Tirzepatide
Batch/lot number present
Lot GT10-062026-6 clearly documented with accession number 2606170070
Dates within normal range
Received 2026-06-17, reported 2026-06-20 (3-day turnaround, reasonable for LC-MS/HPLC testing)
Lab verification uncertain
Freedom Diagnostics Testing appears to be a smaller/newer lab. Website and contact information provided but independent verification of accreditation/certification status not visible on COA
Limited testing scope
Only identity and purity panels performed. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing. Common for basic peptide COAs but limits comprehensive quality assessment
Professional presentation
Document includes company branding, QR code, signature, chromatogram, mass spectrum, and appropriate research-use-only disclaimers
Net content exceeds label claim
Net content 10.72 mg vs labeled 10mg (7.2% overfill). While overfill is common practice, the magnitude should be verified as intentional
