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
- 92
- Confidence
- 93%
- Panels
- 2/7
- Purity (printed)
- 99.7%
Scored high because the document is mostly consistent but carries soft concerns, limited panel coverage (2/7), and 1 soft concern. 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).
FTIR sample spectrum confirms the presence of Tesamorelin with addition of excipient(s)/fillers
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
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 HPLC purity
99.7% purity by HPLC (USP <621>) exceeds ≥98% specification. This is normal for research-grade peptides.
FTIR identity confirmed
FTIR spectrum confirms Tesamorelin presence with excipients/fillers, consistent with formulated peptide product.
Lot number clearly stated
Lot QGQ35N5 clearly documented with BT Sample ID 005000039180656.
Dates are valid and recent
Sample tested 2026-03-07, report issued 2026-03-10. Both dates are valid and logically sequenced.
Testing lab identified
BTLabs (BT Lab Testing), West Palm Beach, FL. Contact information and website provided.
Limited scope: purity/identity only
Testing Purpose explicitly states this COA does NOT provide information on particulate matter, microbial contamination, or endotoxins. This is a purity/identity-focused report, not a comprehensive safety panel.
Professional presentation
Document includes FTIR spectrum, HPLC chromatogram, dual signatures, report number, and verification URL. Formatting is consistent with legitimate analytical lab reports.
