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
- 1/7
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (1/7), 2 soft concerns, and notable note: "Endotoxin testing present". 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.
1 of 7 present · 1 passed · 0 failed · 0 reported · 6 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
Not on this certificate file · core
Compound identity confirmed (e.g. HPLC, mass spec).
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.”
Purity
Not on this certificate file · core
Reported purity percentage for the analyte.
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.”
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.
<5.90 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.

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.
Endotoxin testing present
USP <85> bacterial endotoxin test performed with result <5.90 EU/mL, spike recovery 70%, CVs within acceptable range (8.1% sample, 2.2% spike). This is an endotoxin-specific report.
Limited scope report
This COA only covers endotoxin testing. No purity, identity, heavy metals, microbial, sterility, or residual solvent panels are present on this document. This appears to be a split report focusing solely on endotoxin analysis (note 'ENDO' in sample name). Purity/identity testing may exist in a separate report for this lot.
Established testing laboratory
TrustPointe Analytics LLC is a known third-party analytical testing laboratory in Michigan with verifiable contact information and online verification system.
Batch identification present
Client SID TB202605 and internal Sample ID SPL-3952 both documented.
Publication date valid
Published 2026-05-28, which is before the current date of 2026-09-05. No sample collection date explicitly stated.
Professional presentation
Document includes QR code for verification, dual signatures (President and Managing Director), proper lab letterhead, and structured data presentation consistent with professional analytical reports.
Spike recovery at lower bound
USP <85> spike recovery of 70% is at the minimum acceptable threshold (typical range 50-200%, with 70-130% preferred). While technically passing, this is worth noting for quality assurance.
