Public COA audit
Thymosin alpha-1
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 92
- Confidence
- 93%
- Panels
- 4/7
- Purity (printed)
- 99.952%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (4/7), and 2 soft concerns. To improve: include identity, purity, and endotoxin at minimum.

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.
4 of 7 present · 4 passed · 0 failed · 0 reported · 3 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).
Thymosin alpha-1
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.952%
Heavy metals
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
Pb <0.4, Cd <0.07, Hg <0.4, As <0.17
Microbial
Not on this certificate file
Bioburden / microbial limits testing.
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.”
Endotoxin
Tested · passed · core
LAL or chromogenic endotoxin assay.
< 0.02 EU/mL
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
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.
High purity confirmed
99.952% purity by RP-HPLC with batch conformity testing showing consistent results across two vials (99.968% and 99.951%)
Identity confirmed by LC-MS
Thymosin alpha-1 confirmed by LC-MS with correct molecular formula C129H215N33O55 and CAS 1337515-90-8
Comprehensive testing panel
Includes purity, identity, endotoxin (LAL), heavy metals screening, and batch conformity testing with chromatogram
Batch conformity demonstrated
Two vials tested showing consistent purity and net content within specifications
Same-day analysis
Sample received and analyzed on 2026-02-25, which is before the current date of 2026-09-05
Professional lab presentation
Kovera Labs with verification URL, report number KVR-2026-9E35D5, access code W2LKWDU, and QR code for verification
Missing microbial and sterility testing
No microbial contamination or sterility testing reported; endotoxin testing alone does not cover all microbial concerns
No residual solvent/water content
No testing for residual solvents or water content reported
