Public COA audit
TESAMORELIN
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
- 2/7
- Purity (printed)
- 99.75%
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), 2 soft concerns, and notable note: "High purity values 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.
2 of 7 present · 2 passed · 0 failed · 0 reported · 5 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).
TESAMORELIN confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.847%; 99.608%; 99.745%
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 values reported
Three measurements showing 99.847%, 99.608%, and 99.745% purity. High purity is normal for research peptides and not inherently suspicious.
Identity confirmed
TESAMORELIN identity confirmed with mass measurements (11.12 mg; 11.04 mg; 11.04 mg) indicating triplicate vial testing.
Batch number present
Batch TES10N042325 clearly stated.
Dates are consistent and valid
Testing ordered 25 APR 2025, sample received 29 APR 2025, analysis conducted 30 APR 2025. All dates are sequential and on or before 2026-09-05.
Known testing laboratory
JANOSHIK is a recognized third-party peptide testing laboratory with verification system.
Verification URL provided
Verification key 59RLSWT69CEN provided with URL www.janoshik.com/verify/ for independent verification.
Limited testing scope
This report covers only identity and purity testing. No heavy metals, microbial, endotoxin, sterility, or residual solvent/water testing is included in this particular report. This is common for basic peptide analysis but limits the comprehensiveness of quality assurance.
Minimal detail on methodology
The report does not specify the analytical method used for purity determination (likely HPLC but not explicitly stated). More detailed methodology would strengthen confidence.
Timing & next steps
Practical follow-ups based on document age and gaps.
