Public COA audit
GHK-Cu
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 88
- Confidence
- 87%
- Panels
- 2/7
- Purity (printed)
- 99.634%
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).
RT=1.01, Spectral=1000
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.634% (range 99.611-99.752% 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 all vials
Purity ranges from 99.611% to 99.752% across five tested vials (SPL-3752 and four sub-samples), with excellent consistency. System suitability at 0.4% RSD indicates robust analytical method.
Identity confirmed by dual methods
Identity verified by both retention time (RT ~1.00-1.01) and spectral match (1000 score), with coelution control passing (1000). This is standard practice for peptide identity confirmation.
Clear batch identification
Client SID CU202605 clearly stated. Internal lab IDs (SPL-3752 series) are traceable.
Issue date within acceptable range
Published 2026-05-13, which is before today (2026-09-05). No sample collection date provided, but issue date is valid.
Lab information complete with verification system
TrustPointe Analytics LLC (Dorr, MI) with full contact details, verification URL (TrustPointeLIMS.com), and unique verification key (J4CKPF8K3KW9). Dual signatures from President and Managing Director.
Limited scope: purity/identity only
This COA covers purity and identity testing only. No heavy metals, microbial, endotoxin, sterility, or residual solvent/water panels are present. This is a purity/identity-scoped report and does not indicate whether the vendor/lot has separate testing for other panels.
Professional presentation with photo attachment
Clean, professional layout with TrustPointe branding, QR code for verification, and photo attachment of the five vials on page 2. Formatting is consistent with a legitimate analytical lab report.
