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).
Tesamorelin
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.87%
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.
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
99.87% purity by HPLC-UV is excellent and typical for research-grade peptides
Identity confirmed by LC-MS
Mass spectrometry confirmation provided with spectrum showing expected molecular ion peaks for Tesamorelin
Endotoxin testing included
USP <85> compliant endotoxin testing with two replicates, both passing at ≤0.05 EU/mL sensitivity
Clear lot identification
Lot number TESM-052026-4 with accession number 2605130118 and search code provided
Appropriate turnaround time
Received 2026-05-13, reported 2026-05-14 - one day turnaround is reasonable
Limited lab verification information
Freedom Diagnostics Testing website and email provided, but no physical address, accreditation details, or analyst credentials beyond 'Principal Chemist' signature
Incomplete testing panel
Missing heavy metals, microbial contamination, sterility, and residual solvent/water content testing - common for basic peptide COAs but limits comprehensive quality assessment
Generic client designation
Client listed only as 'Wholesale' rather than specific company name, which is unusual for traceable quality documentation
