Public COA audit
Thymosin Alpha-1 · Thymalfasin
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 72
- Confidence
- 85%
- Panels
- 5/7
- Purity (printed)
- 99.6%
Scored moderately because the document is mostly consistent but carries soft concerns, broad panel coverage (5/7), 4 soft concerns, and notable note: "High HPLC purity". To improve: prefer labs with a public verification portal.

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).
Amino acid profile confirmed, specific rotation -110.0°
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.6%
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.
Aerobe <1000cfu/g, Mould & Yeast <100cfu/g
Endotoxin
Tested · passed · core
LAL or chromogenic endotoxin assay.
<10EU/mg
Sterility
Not on this certificate file
Sterility testing where applicable.
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.”
Residual solvent / water
Tested · passed
Residual solvents or water content limits.
Water 3.1%, Acetic acid 0.04%, acetonitrile <0.041%, dichloromethane <0.06%, N,N-Dimethylformamide <0.088%
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.
High HPLC purity
99.6% purity by HPLC is excellent and normal for research-grade peptides
Comprehensive identity testing
Amino acid profile with all expected residues confirmed, specific rotation within specification
Endotoxin testing present
Bacterial endotoxin result <10EU/mg documented
Residual solvents tested
Water content, acetic acid, and organic solvent residues all within specifications
No lab identification
Document does not identify the testing laboratory name, address, or accreditation
No verification mechanism
No URL, QR code, or reference number provided for independent verification
Watermark present
Document contains a 'SAMPLE' watermark overlay, which may indicate this is a template or draft rather than a final issued COA
Retest date provided
Retest date of 2026-01-06 is reasonable (2-year stability from production date)
Batch information complete
Batch number, production date, and storage conditions clearly documented
Heavy metals not tested
No heavy metals panel present in this report
Timing & next steps
Practical follow-ups based on document age and gaps.
coa age
This COA was issued over a year ago (972 days) — consider whether a retest is warranted for this batch.
