Public COA audit
TB-500 · TB4
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 92
- Confidence
- 88%
- Panels
- 2/7
- Purity (printed)
- 99.766%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), and 1 soft concern. 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.
2 of 7 present · 2 passed · 0 failed · 0 reported · 5 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).
ID by RT: 1.00, ID by Spectral: 1000
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.727-99.823% across 5 vials
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
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
Not on this certificate file · core
LAL or chromogenic endotoxin assay.
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.”
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.

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 across multiple vials
Five vials tested with purity ranging 99.727-99.823%, consistent with research-grade peptide standards. Assay values 9.551-9.999 mg per 10mg nominal.
Dual identity confirmation
Identity confirmed by both retention time (RT=1.00) and spectral matching (score=1000) for all five vials using method TM-1006.
Clear batch identification
Client SID TB202605 clearly stated. Internal lab IDs SPL-3956 through SPL-3956-S04 for five vials.
Publication date valid
Published 2026-05-28, which is before the current date 2026-09-05. No sample receipt date provided.

Purity/identity scope only
This COA covers purity and identity testing only. No heavy metals, microbial, endotoxin, sterility, or residual solvent/water panels present in this report. This is common for purity-focused testing but buyers should verify if additional safety panels exist in separate reports.
Professional presentation
Document includes QR code for verification, dual signatures (Ashlee Lust, President; Joshua Lust, Managing Director), system suitability data (0.7% RSD), coelution control, and photo attachment of tested vials.
