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.
1 of 7 present · 1 passed · 0 failed · 0 reported · 6 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
Not on this COA · core
Compound identity confirmed (e.g. HPLC, mass spec).
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Purity
Not on this COA · core
Reported purity percentage for the analyte.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Heavy metals
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
Pb <0.4 ppm, As <0.17 ppm, Cd <0.07 ppm, Hg <0.4 ppm
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.
Heavy metals only - incomplete COA
This document only contains heavy metals analysis (ICP-MS). A complete peptide COA typically includes identity confirmation (MS, NMR) and purity analysis (HPLC). This appears to be a supplemental panel rather than a full COA.
Heavy metals panel complete
All four critical heavy metals (Pb, As, Cd, Hg) tested and passed with results well below acceptance limits. Spike recovery data (94-109%) confirms method suitability.
Lab verification needed
Kovera Labs is listed with verification URL koveralabs.com/verify and access code 508556. Lab existence and accreditation should be independently verified.
Test date valid
Test date of February 25, 2026 is within acceptable range (before current date of July 28, 2026).
Batch information present
Lot/Batch TA202602 clearly identified with product name Thymosin alpha-1, 10 mg strength, lyophilized condition.
Professional presentation
Document has professional layout with clear sections, QR code for verification, proper authorization signatures (Liam Clarke QC Analyst, David Cohen Quality Director), and quality control metrics.
