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).
Retatrutide confirmed, precursor [M+5H]5+ 947.90 Da, MRM transitions 947.9›136.1 and 947.9›110.1
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.47%
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
99.47% purity meets specification (≥98%) and is typical for research-grade peptides analyzed by LC-MS/MS
Positive identity confirmation
Compound confirmed as Retatrutide via LC-MS/MS with appropriate precursor ion (947.90 Da [M+5H]5+) and MRM transitions, retention time 3.634 min
Batch information complete
Lot number R-3001, Report No. COA-2026-SC-00311, Sample ID RET-095 clearly documented
Dates consistent and recent
Received 2026-07-15, analyzed and issued 2026-07-18 (3-day turnaround), all dates are on or before today (2026-07-29)
Testing lab identified
Analysis performed by SideChain Analytics, verification URL and QR code provided (Peptidetestcanada.ca/verify, code PTC-736LEW5F)
Limited testing scope
Only identity and purity panels performed; no heavy metals, microbial, endotoxin, sterility, or residual solvent/water testing. This is common for basic research peptide testing but limits comprehensive quality assessment
Professional presentation
Well-formatted COA with clear sections, chromatogram, sample photograph, appropriate disclaimers for research use only, and detailed methodology
