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.
4 of 7 present · 4 passed · 0 failed · 0 reported · 3 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).
Tesamorelin
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.62%
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
Tested · passed
Bioburden / microbial limits testing.
No Detectable Microbial DNA
Endotoxin
Tested · passed · core
LAL or chromogenic endotoxin assay.
Pass (both replicates)
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 99.62% with individual vial measurements of 99.65% and 99.58%. This is normal for research-grade peptides.
Identity confirmed by LC-MS
Tesamorelin identity confirmed via liquid chromatography-mass spectrometry with mass confirmation spectrum provided.
Comprehensive testing suite
Document includes identity, purity, endotoxin, and microbial testing. Heavy metals, sterility, and residual solvent panels not present but this is common for peptide COAs.
Batch information present
Lot number TES10-062026-1 clearly stated with accession number 2606110521 and search code.
Dates within normal range
Received 2026-06-11, reported 2026-06-15 (4-day turnaround). Both dates are before today (2026-07-28).
Lab verification limited
Freedom Diagnostics Testing appears to be a newer or smaller lab. Website and contact information provided but independent verification of accreditation/certification not visible on document.
Professional presentation
Document includes chromatogram, mass spectrum, detailed methodology, appropriate disclaimers, and signature. Layout is consistent with legitimate testing reports.
Signature lacks credentials
Document signed by 'Principal Chemist' but no name, credentials (PhD, MS), or certification numbers provided. Legitimate labs typically include chemist identification.
