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).
ID Confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.88%
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 chromatographic purity
99.88% purity by HPLC-UV-MS is excellent and typical for research-grade peptides
Identity confirmed by mass spectrometry
Mass spectrum matches reference standard for Retatrutide (CAS 2381089-83-2), with characteristic m/z peaks at 1184 and 1578
Clear batch identification
Lab # 131088, Project 135559, Test Certificate ID ch6vmzw
Dates are consistent and valid
Sample received 2025-12-08, tested 2025-12-14, report issued 2025-12-30 - all dates are logical and within acceptable timeframes
Established testing laboratory
Krause Analytical LLC is a known peptide testing laboratory in Austin, TX with verification URL provided
Limited testing panels
Only identity and purity panels performed. Methods for endotoxin and heavy metals are described on page 3 but no results are shown, suggesting these tests were not actually conducted for this sample
Professional presentation
Document includes chromatogram, mass spectrum comparison, detailed methods summary, and proper laboratory signatures
