Public COA audit
PT-141
Audited September 5, 2026
Missing panels or key metadata — not enough evidence to treat this as a full certificate.
- Legitimacy
- 62
- Confidence
- 78%
- Panels
- 1/7
- Purity (printed)
- 99.8%
Scored lower because the file is incomplete or not a full COA, limited panel coverage (1/7), 3 soft concerns, and notable note: "High purity reported". To improve: upload the full certificate (or the matching sibling purity/endotoxin report) and 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.
1 of 7 present · 0 passed · 0 failed · 1 reported · 6 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
Not on this certificate file · core
Compound identity confirmed (e.g. HPLC, mass spec).
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.”
Purity
Tested · result on file · core
Reported purity percentage for the analyte.
99.800%
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
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 purity reported
99.800% purity is within normal range for research peptides and is not suspicious by itself
No identity confirmation method stated
Report shows purity but does not explicitly state identity confirmation method (e.g., MS, NMR)
Limited testing scope
This report only covers purity assessment. No identity, heavy metals, microbial, endotoxin, sterility, or residual solvent/water testing is shown on this document
Known testing laboratory
Janoshik Analytical is a recognized third-party peptide testing laboratory
Verification URL provided
Document includes verification URL (www.janoshik.com/verify/) with unique key FVK75CTTF2XD for independent verification
Batch number present
Batch PT141-0003 clearly stated
Dates are consistent and valid
Testing ordered 29 MAR 2025, sample received 02 APR 2025, analysis conducted 03 APR 2025 - all dates are logical and on or before 2026-09-05
Minimal detail provided
Report format is very basic with limited technical detail about testing methodology or acceptance criteria
Timing & next steps
Practical follow-ups based on document age and gaps.
