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).
Conform (Appearance, Solubility)
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.5%
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
Tested · passed
Residual solvents or water content limits.
Water: 4.1%, Acetic Acid: 8.2%
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 HPLC purity reported
99.5% peptide purity by HPLC with 0.5% total impurities and 0.5% largest single impurity, all within specification
Identity tests present
Appearance and solubility tests conform to specification
Batch information complete
Batch No. 2024030601-1, CAS 1627580-64-6, molecular formula and weight provided
No laboratory identification
No lab name, address, accreditation, or contact information provided. Only analyst names listed: Cheng Diya, Guo Sirui, Wang Haiyan
Limited testing scope
Missing heavy metals, microbial, endotoxin, and sterility testing. Only purity, identity, and residual solvent/water panels present
Watermark present
Document has 'Deo Peptides' watermark overlay, which is unusual for official COAs but may indicate sample/draft status
Generic template appearance
Document uses basic table format without lab branding, letterhead, or accreditation logos
Timing & next steps
Practical follow-ups based on document age and gaps.
