Original certificate
Embedded copy of the stored COA PDF or image. Download it for your records — PeptIQ’s audit is separate from the lab document itself.
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.
5 of 7 present · 5 passed · 0 failed · 0 reported · 2 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).
GHK-Cu
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.938%
Heavy metals
Not on this certificate file
Lead, arsenic, cadmium, mercury, or similar limits.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Microbial
Tested · passed
Bioburden / microbial limits testing.
No Growth
Endotoxin
Tested · passed · core
LAL or chromogenic endotoxin assay.
< 0.06 EU/mL
Sterility
Tested · passed
Sterility testing where applicable.
No Growth
Residual solvent / water
Not on this certificate file
Residual solvents or water content limits.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
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 on this file
Not on this certificate file. Lowers file thoroughness; a sibling endotoxin/purity report for the same lot may still exist. PeptIQ’s score still factors coverage.
Findings
Evidence-linked observations from this audit.
Excellent purity with batch consistency
Batch average purity of 99.938% with tight distribution across 5 vials (99.886-99.959%). This is normal for high-quality research peptides.
Identity confirmed by LC-MS
Compound identity verified as GHK-Cu using LC-MS methodology.
Comprehensive testing panel
Document includes purity (RP-HPLC), identity (LC-MS), endotoxin (LAL), and microbial sterility testing. Heavy metals and residual solvents not included in this report.
Clear batch identification
Batch number CU202604 clearly stated with individual vial testing results provided.
Professional lab presentation
Kovera Labs report with verification URL (koveralabs.com/verify), report number KVR-2026-B787A6, access code PUKJQ6Q, and lab director signature.
Professional document structure
Well-formatted COA with clear sections, chromatogram included, product photo, and QR code for verification.
Heavy metals and residual solvents not tested
This report does not include heavy metals or residual solvent/water content testing. These may be available in separate reports or not part of this vendor's standard panel.
