Public COA audit
Semaglutide
Audited September 5, 2026
Several fields check out, but we found issues worth reviewing before you rely on this document.
- Legitimacy
- 68
- Confidence
- 82%
- Panels
- 1/7
- Purity (printed)
- 99.75%
Scored lower because the document is mostly consistent but carries soft concerns, limited panel coverage (1/7), 1 critical finding, and notable note: "Minimal documentation". 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.
99.669%; 99.806%; 99.871%
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.
Minimal documentation
Report lacks detailed methodology, chromatograms, specifications, or pass/fail criteria. Very basic format compared to comprehensive COAs.
High purity reported
Three measurements showing 99.669%, 99.806%, and 99.871% purity (average ~99.75%). This is within normal range for research-grade peptides.
Batch/lot number missing
The batch field explicitly states 'Unknown', which is highly irregular for a legitimate COA. Batch traceability is essential for quality control.
No identity confirmation
No identity testing method (MS, NMR, etc.) is documented. Only purity values are provided, with no confirmation that the compound is actually Semaglutide.
Limited testing scope
This report only covers purity assessment. No identity, heavy metals, microbial, endotoxin, sterility, or residual solvent testing is included. This is a purity-only report.
Verification system provided
Janoshik provides a verification URL (www.janoshik.com/verify/) with unique key Y8GCBEX7BNHS for authentication. Lab is known in the peptide testing community.
Dates are consistent
Testing ordered 06 JUN 2024, sample received 11 JUN 2024, analysis conducted 08 JUL 2024. Timeline is logical and all dates are in the past relative to 2026-09-05.
Timing & next steps
Practical follow-ups based on document age and gaps.
coa age
This COA was issued over a year ago (789 days) — consider whether a retest is warranted for this batch.
