Public COA audit
KLOW Blend (TB-500 + BPC-157 + KPV + GHK-Cu) · TB-500
Audited September 3, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 72
- Confidence
- 83%
- Panels
- 3/7
- Purity (printed)
- 99.7%
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (3/7), 4 soft concerns, and notable note: "High HPLC purity reported". To improve: include identity, purity, and endotoxin at minimum and prefer labs with a public verification portal.

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 · 2 passed · 0 failed · 1 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).
Conforms
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.7%
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
Not on this certificate file · core
LAL or chromogenic endotoxin assay.
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.”
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
Tested · result on file
Residual solvents or water content limits.
1.62% acetic acid
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 reported
99.7% purity by HPLC is within normal range for research peptides and is supported by identity confirmation via MS
Identity verification present
MS fingerprint confirmation for each component of the blend reported as conforming
Batch information complete
Lot number 78928 with manufacturing date June 2, 2026 and retest date June 2, 2028
Issue date valid
Issue date of June 2, 2026 is on or before the current date of September 3, 2026
Lab verification not possible
Novo Pharmaceutical Co., Ltd. is not a widely recognized third-party testing laboratory. No verification URL or contact information provided to independently confirm authenticity
Limited testing scope
COA lacks heavy metals, microbial, endotoxin, and sterility testing. While not uncommon for research-grade peptides, more comprehensive testing would increase confidence
Generic presentation
Document uses generic certification badges (GMP, ISO, QOA) without specific accreditation numbers or verifiable credentials beyond the ISO 9001:2015 reference
Manufacturer as testing lab
The COA appears to be issued by the manufacturer rather than an independent third-party laboratory, which reduces objectivity
