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).
FTIR sample spectrum confirms the presence of GLOW with addition of excipient(s)/fillers
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.7%
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
Not on this COA · core
LAL or chromogenic endotoxin assay.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
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 HPLC purity achieved
99.7% purity meets specification of ≥98%, which is normal for research peptides
Identity confirmed by FTIR and HPLC
FTIR spectrum confirms presence of GLOW peptide blend with excipients; HPLC shows three distinct peptide peaks
Clear batch identification
Lot number WL-GLOW-P00520 and BT Sample ID 005000040403821 clearly documented
Dates are logical and current
Sample tested 6/8/2026, report issued 6/12/2026 - both dates are reasonable and within normal timeframes
Professional lab presentation
BTLabs with complete contact information, dual scientist signatures, QR code, and professional formatting
Limited testing scope
COA explicitly states it does not provide information on particulate matter, microbial contamination, or endotoxins. No heavy metals, sterility, or residual solvent testing performed
Potency below labeled claim
Total peptide content 71.6 mg (102.3% of labeled 70mg) but individual peptides show GHK-Cu at 65.1%, TB-500-Frg at 17.9%, and BPC-157 at 19.2% of their respective portions - specification is 90-110%
Complete analytical data
Includes FTIR spectrum, HPLC chromatogram, peak table, mass measurement, and visual description with photo
