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).
Glutathione confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.73%
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
99.73% purity by HPLC-UV is within normal range for research-grade peptides
Identity confirmed
Mass spectrometry data shows expected [M+H]+ peak at 308.00 m/z with chromatogram showing single major peak
Lab verification uncertain
Freedom Diagnostics appears to be a smaller testing facility; independent verification of lab credentials recommended
Limited testing scope
COA only includes identity and purity testing; no heavy metals, microbial, endotoxin, sterility, or solvent/water content panels
Batch information present
Lot number 25042801-H clearly stated with net peptide content of 1447.7 mg
Dates appropriate
Received 2025-07-22, reported 2025-07-23 (one-day turnaround is reasonable for HPLC-MS analysis)
Professional presentation
Document includes chromatogram, mass spectrum, product photos, and signatory information
Timing & next steps
Practical follow-ups based on document age and gaps.
