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
- 88%
- Panels
- 3/7
- Purity (printed)
- 99.8%
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (3/7), 2 soft concerns, and notable note: "High HPLC purity". 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.
18.7 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 is excellent and within normal range for research-grade peptides
FTIR confirmation
Identity confirmed via FTIR spectroscopy with characteristic peptide bands; excipients noted
Potency significantly exceeds specification
HPLC potency assay shows 122-138% of labeled 10mg (12.2-13.8mg actual), exceeding the 90-110% specification range. This overfill is common in research peptides but technically fails the stated spec.
Endotoxin testing present
Separate endotoxin report (page 3) shows gel clot LAL test with 18.7 EU/vial result, well below 40 EU/vial limit
Consistent lot number
Lot CR-TB510-2603-1 consistent across both purity and endotoxin reports
Dates are valid
Sample date 2026-04-02, issue date 2026-04-05, endotoxin test 2026-04-08, all on or before current date 2026-09-05

Professional multi-page report
Three-page report with FTIR spectrum, HPLC chromatogram, and separate endotoxin certificate; signatures from two scientists
Limited scope explicitly stated
Testing purpose explicitly states it does not provide information on particulate matter or microbial contamination (sterility). Heavy metals and residual solvents not tested.
