Public COA audit
PT-141
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
- 1/7
- Purity (printed)
- 99.41%
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (1/7), 2 soft concerns, and notable note: "High purity reported". 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.
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.
99.271%; 99.546%; 99.413%
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.

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
Three replicate measurements show purity values of 99.271%, 99.546%, and 99.413% (average ~99.41%). This is within normal range for research-grade peptides and shows good analytical reproducibility.
No identity confirmation method stated
The report shows purity data but does not explicitly state the identity confirmation method (e.g., MS, NMR). The test description only mentions 'Assessment of a peptide vial or vials' without specifying analytical techniques.
Limited scope - purity only
This report appears to be a purity-focused analysis. No heavy metals, microbial, endotoxin, sterility, or residual solvent/water testing is documented on this page. This may be a split report or basic purity-only service.
Janoshik Analytical - known testing lab
Janoshik Analytical is a recognized third-party testing laboratory in the peptide/performance-enhancing substance community. The report includes verification URL and unique key (N52TZ2HP7E8M).
Dates are consistent and reasonable
Testing ordered 24 APR 2025, sample received 29 APR 2025, analysis conducted 30 APR 2025. Timeline is logical and all dates are in the past relative to 2026-09-05.
Batch number present
Batch PT15n041725 is clearly stated and follows a logical naming convention (PT prefix, year/date components).
Professional formatting with QR code
Report includes professional layout, QR code for verification, signature, and contact information. Formatting is consistent with legitimate lab reports.
Timing & next steps
Practical follow-ups based on document age and gaps.
