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
- 92
- Confidence
- 93%
- Panels
- 3/7
- Purity (printed)
- 99.8%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (3/7), 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.
3 of 7 present · 3 passed · 0 failed · 0 reported · 4 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).
FTIR sample spectrum confirms the presence of TB-500 with addition of excipient(s)/fillers
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.8%
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
Tested · passed · core
LAL or chromogenic endotoxin assay.
18.3 EU/vial (limit: 40 EU/vial)
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 HPLC purity
99.8% purity by HPLC (USP <621>) exceeds specification of ≥98%. This is normal for research-grade peptides.
FTIR identity confirmed
FTIR spectrum confirms TB-500 presence with excipients/fillers noted. Chromatogram and spectrum provided on page 2.
Lot number present
Lot CR-WOLF10-2603-1 clearly stated. Multiple vials tested (59.1, 55.1, 49.3 mg masses recorded).
Dates consistent
Date tested 4/2/2026, issue date 4/5/2026. Endotoxin test dated 4/8/2026, issued 4/10/2026. All dates are reasonable and sequential.
Lab information complete
BTLabs, West Palm Beach FL. Contact info, website (https://btlabtesting.com), report numbers, QR codes, and dual scientist signatures present.
Endotoxin testing performed separately
This is a split-report set: pages 1-2 cover purity/identity/potency (report IF-824-QSA-TR006-BTL26130-11), page 3 is a separate endotoxin report (IF-824-QSA-TR006-BTL26130-30) for the same lot. Endotoxin result: 18.3 EU/vial, passing 40 EU/vial limit.
Heavy metals, microbial, sterility, residual solvents not tested
Testing purpose explicitly states this does not cover particulate matter, microbial contamination, or presence of endotoxins (on the purity report). Endotoxin was tested separately. Heavy metals, sterility, and residual solvents/water content not included in either report.
Professional formatting
Multi-page report with consistent headers, watermarks, signatures, QR codes, and USP method references. FTIR and HPLC chromatograms included.
