Public COA audit
Kisspeptin
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 92
- Confidence
- 93%
- Panels
- 3/7
- Purity (printed)
- 99.8%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (3/7), and 1 soft concern. 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 Kisspeptin 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.
15.6 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 achieved
99.8% purity by HPLC (USP <621>) meets specification of ≥98%. This is normal for research-grade peptides.
Identity confirmed by FTIR
FTIR spectrum confirms Kisspeptin with excipients/fillers present, consistent with formulated peptide product.
Endotoxin testing performed separately
Endotoxin testing documented in separate report (IF-824-QSA-TR006-BTL26130-35) dated 4/10/2026, showing 15.6 EU/vial (PASS, limit 40 EU/vial). This is a split-report format common for comprehensive testing.
Potency within specification
HPLC potency assay shows 104.8-108.9% of labeled 10 mg, within 90-110% specification range.
Dates are current and consistent
Issue date 4/5/2026, test date 4/2/2026, endotoxin report dated 4/10/2026. All dates are on or before 2026-09-05 and logically sequenced.
Lab information complete
BTLabs, West Palm Beach FL, with contact info, website, report numbers, QR codes, and dual scientist signatures on both reports.
Professional multi-page report with supporting data
Includes FTIR spectrum, HPLC chromatogram, detailed mass/potency measurements, and separate endotoxin report. Formatting is consistent with professional analytical lab standards.
Heavy metals, microbial, sterility, and residual solvent testing not included
These panels are not present in this report set. The testing purpose statement explicitly notes the scope excludes particulate matter and microbial contamination (page 1), though endotoxin testing was performed separately.
