Public COA audit
KPV
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 72
- Confidence
- 85%
- Panels
- 3/7
- Purity (printed)
- 99.8%
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (3/7), 2 soft concerns, and notable note: "High HPLC purity". To improve: include identity, purity, and endotoxin at minimum.

Original certificate
Embedded copy of the stored COA PDF or image. Download it for your records — PeptIQ’s audit is separate from the lab document itself.
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 KPV with addition of excipient(s)/fillers
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.8%
Heavy metals
Not on this certificate file
Lead, arsenic, cadmium, mercury, or similar limits.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Microbial
Not on this certificate file
Bioburden / microbial limits testing.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Endotoxin
Tested · passed · core
LAL or chromogenic endotoxin assay.
18.3 EU/vial (limit: 40 EU/vial)
Sterility
Not on this certificate file
Sterility testing where applicable.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
Residual solvent / water
Not on this certificate file
Residual solvents or water content limits.
No evidence on this file. Vendors sometimes publish separate purity and endotoxin reports for the same lot — check the brand page before treating this as “never tested.”
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 on this file
Not on this certificate file. Lowers file thoroughness; a sibling endotoxin/purity report for the same lot may still exist. PeptIQ’s score still factors coverage.
Findings
Evidence-linked observations from this audit.
High HPLC purity
99.8% purity by HPLC is excellent and within normal range for research-grade peptides
FTIR identity confirmed
FTIR spectrum confirms KPV peptide identity with excipients/fillers present as expected
Potency below specification
HPLC potency results show 73-98.9% of labeled 10mg claim (spec: 90-110%), with one measurement at 73% failing the lower bound
Endotoxin testing passed
Separate endotoxin report (page 3) shows 18.3 EU/vial, well below 40 EU/vial limit via gel clot LAL test
Limited scope - no heavy metals, microbial, or sterility
COA explicitly states it does not provide information on particulate matter, microbial contamination beyond endotoxins, or sterility testing
Batch number consistent
Lot CR-KPV10-2603-1 appears on all three pages with consistent sample descriptions
Dates are valid and sequential
Sample tested 4/2/2026, purity report issued 4/5/2026, endotoxin tested 4/8/2026, endotoxin report issued 4/10/2026 - all dates are sequential and on or before today (2026-09-05)
Lab information appears complete
BTLabs with full contact information, West Palm Beach FL address, phone, email, website URL provided
Professional formatting with chromatograms
Report includes FTIR spectrum, HPLC chromatogram, detailed peak table, dual scientist signatures, QR code, and consistent branding
