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 COA
Lead, arsenic, cadmium, mercury, or similar limits.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Microbial
Tested · passed
Bioburden / microbial limits testing.
No Detectable Microbial DNA
Endotoxin
Tested · passed · core
LAL or chromogenic endotoxin assay.
Pass (both replicates)
Sterility
Not on this COA
Sterility testing where applicable.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Residual solvent / water
Not on this COA
Residual solvents or water content limits.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
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
Not on this certificate. Lowers thoroughness; you decide if that panel matters for your use case. PeptIQ’s score still factors coverage.
Findings
Evidence-linked observations from this audit.
High purity confirmed
HPLC-UV purity of 99.68% (average of 99.60% and 99.75%) is within normal range for research peptides
Identity confirmed by LC-MS
All three peptides (GHK-Cu, Thymosin Beta-4, BPC-157) confirmed with mass spectrometry data shown
Batch information present
Lot number GLOW-062026-4, Accession 2606030675
Dates within acceptable range
Received 2026-06-03, Reported 2026-06-07 (4-day turnaround)
Lab verification uncertain
Freedom Diagnostics Testing website and contact provided, but independent verification of lab accreditation/credentials not possible from document alone
Some standard panels missing
Heavy metals, sterility, and residual solvent/water content testing not included. This is common for some labs but reduces comprehensiveness
Professional presentation
Document includes chromatogram, mass spec data, detailed methodology, and appropriate disclaimers for research use
Generic email domain
Contact email uses @FreedomDiagnostics.net rather than company's stated .com domain, minor inconsistency
