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
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.92%
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 99.92% (average of two vials: 99.91% and 99.93%) is within normal range for research-grade peptides
Identity confirmed by LC-MS
Mass spectrometry confirmation provided with chromatogram and mass spectrum showing GHK-Cu peaks
Batch/lot number present
Lot GHK100-062026-1 with accession number 2606190037 and search code Whol2606190037
Dates are consistent
Received 2026-06-19, reported 2026-06-22 (3-day turnaround is reasonable)
Lab verification limited
Freedom Diagnostics Testing website and contact provided, but no independent accreditation badges (ISO, GMP) visible on this COA
Multiple safety panels included
Endotoxin testing (USP <85> compliant) and microbial analysis (PCR) both passed; heavy metals and residual solvents not tested
Heavy metals and residual solvents not tested
COA does not include heavy metals or residual solvent/water content analysis, which are common for comprehensive peptide testing
Professional presentation
Document includes chromatogram, mass spectrum, signature, QR code, and detailed methodology descriptions
