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).
Kisspeptin confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.82%
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 purity confirmed
99.82% purity by HPLC is within normal range for research-grade peptides
Identity confirmed by mass spectrometry
LCMS/MS data shows expected mass ions [M+2H]2+ at 651.58 and [M+H]+ at 1302.18/1304.18, consistent with Kisspeptin
Limited online presence
Freedom Diagnostics appears to be a smaller testing facility with minimal verifiable third-party information available online
Limited testing scope
COA only includes identity and purity testing; no heavy metals, microbial, endotoxin, sterility, or residual solvent/water analysis
Non-standard presentation
Document layout and formatting differ from typical commercial analytical lab COAs; includes product photos which is unusual
Batch number present
Lot number KISS08042025-J is clearly stated
Dates are reasonable
Received 8/5/2025, reported 8/6/2025 - one-day turnaround is fast but plausible for identity/purity only
