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).
FTIR sample spectrum confirms the presence of Kisspeptin with addition of excipient(s)/fillers
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.8%
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.
15.6 EU/vial (limit: 40 EU/vial)
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 confirmed
HPLC purity of 99.8% meets specification (≥98%), which is normal for research-grade peptides
Identity confirmed by FTIR
FTIR spectrum confirms Kisspeptin with excipients/fillers present, consistent with formulated peptide product
Batch/lot number present
Lot CR-KISS10-2603-1 clearly documented with BT Sample IDs 005000039491552 (main COA) and 005000039491624 (endotoxin test)
Dates are consistent and valid
Sample tested 4/2/2026, main COA issued 4/5/2026, endotoxin test dated 4/8/2026 and issued 4/10/2026. All dates are logical and on or before 2026-07-28

Multiple analytical panels performed
Identity (FTIR), purity (HPLC), potency (HPLC), and endotoxin testing all performed. Heavy metals, microbial, sterility, and residual solvent/water testing not included, which is common for research peptide COAs
Endotoxin testing performed separately
Separate endotoxin COA (page 3) shows result of 15.6 EU/vial, well below the 40 EU/vial limit
Professional formatting with supporting data
Multi-page COA includes FTIR spectrum, HPLC chromatogram, potency assay data, peptide-to-excipient ratios, and detailed test results. QR code and watermarks present
