Public COA audit
TB-500
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 72
- Confidence
- 83%
- Panels
- 2/7
- Purity (printed)
- 99.86%
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), 3 soft concerns, and notable note: "High purity across three vials". 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).
RT match 1.00, Spectral match 1000
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.823%, 99.772%, 99.986%
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.
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 across three vials
Three vials tested with purity values of 99.823%, 99.772%, and 99.986%. High purity is normal for research peptides and not a red flag by itself.
Identity confirmed by dual methods
TB-500 identity verified by both retention time (RT) and spectral matching across all three samples.
Batch/lot number present
Client SID TB202601 clearly documented.
Sample date not specified
COA shows publication date (2026-01-14) but does not explicitly state when the sample was received or tested.
Lab information complete
TrustPointe Analytics LLC with full address, contact information, and verification URL provided.
Limited testing scope - purity/identity only
This COA covers purity and identity testing only. No heavy metals, microbial, endotoxin, sterility, or residual solvent/water testing is included in this report. This may be a purity-scoped report; the vendor may have separate reports for other panels.
Professional formatting with signatures
Document includes QR code for verification, dual signatures (Ashlee Lust, President; Joshua Lust, Managing Director), and photo attachment of tested vials.
Assay values exceed label claim
All three vials show assay values (10.896 mg, 10.487 mg, 10.623 mg) exceeding the 10mg label claim. While this can occur with overfill, it warrants verification that the vendor intended this or if there's a measurement/labeling discrepancy.
