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.
3 of 7 present · 3 passed · 0 failed · 0 reported · 4 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/KPV/BPC-157/Thymosin Beta-4 confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.78% (Vial 1), 99.77% (Vial 2), Average 99.775%
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
Not on this COA
Bioburden / microbial limits testing.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Endotoxin
Tested · passed · core
LAL or chromogenic endotoxin assay.
≤0.05 EU/mL (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
Purity values of 99.78% and 99.77% for duplicate vials are consistent and within normal range for research-grade peptides. HPLC-UV method appropriate.
Mass spec confirmation present
Mass spectrometry data shows expected m/z peaks for all four peptides (GHK-Cu, KPV, BPC-157, Thymosin Beta-4) with charge states labeled. Chromatogram shows separation of components.
Lot number present
Lot CRKL-80-1025-01 clearly stated. Product is a blend formulation (Klow 80mg) with quantified content for each peptide component in two vials.
Dates reasonable
Received 11/6/2025, Reported 11/8/2025 - two-day turnaround is plausible for routine HPLC-MS testing.
Lab identification present
Freedom Diagnostics with searchable verification URL (FreedomDiagnosticsTesting.com) and contact email. Signed by Stephen Schmidt, Principal Chemist. US-based lab claim.
Limited panel coverage
Only identity, purity, and endotoxin panels present. No heavy metals, microbial, sterility, or residual solvent testing reported. This is common for basic peptide COAs but limits comprehensive quality assessment.
Professional presentation
Document includes company branding, accession number (2511060021), search code, product photos, chromatogram, and mass spectrum. Layout is organized and includes appropriate disclaimers about research use only.
