Public COA audit
GHK-Cu · Thymosin Beta-4
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 72
- Confidence
- 85%
- Panels
- 4/7
- Purity (printed)
- 99.68%
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (4/7), 3 soft concerns, and notable note: "High purity confirmed". 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.
4 of 7 present · 4 passed · 0 failed · 0 reported · 3 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).
GHK-Cu/Thymosin Beta-4/BPC-157
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.68%
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
Tested · passed
Bioburden / microbial limits testing.
No Detectable Microbial DNA
Endotoxin
Tested · passed · core
LAL or chromogenic endotoxin assay.
Replicate 1: Pass, Replicate 2: Pass
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 confirmed
Average purity of 99.68% across two vials (99.60% and 99.75%) is consistent with quality research-grade peptides
Identity confirmed by LC-MS
All three peptides (GHK-Cu, Thymosin Beta-4, BPC-157) confirmed with mass spectrometry data shown
Endotoxin testing performed
LAL assay per USP <85> with two replicates both passing, sensitivity ≤0.05 EU/mL
Microbial testing performed
PCR-based assay detected no microbial DNA
Lab verification unclear
Freedom Diagnostics Testing website and contact information provided, but independent verification of lab accreditation/credentials not possible from document alone
Blend product complexity
Three-peptide blend with individual quantification shown for each component across two vials; net content values show reasonable variation between vials
Missing heavy metals and residual solvent panels
No heavy metals or residual solvent/water content testing shown; these are common but not universal panels for research peptides
Dates are valid
Received 2026-06-03, Reported 2026-06-07 (4-day turnaround); both dates are on or before current date 2026-09-05
