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
- 3/7
- Purity (printed)
- 99.87%
Scored moderately because the document is mostly consistent but carries soft concerns, limited panel coverage (3/7), 2 soft concerns, and notable note: "High purity confirmed". 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.
3 of 7 present · 3 passed · 0 failed · 0 reported · 4 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.
99.87%
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
Tested · passed · core
LAL or chromogenic endotoxin assay.
Replicate 1: Pass, Replicate 2: Pass, Assay Sensitivity: ≤0.05 EU/mL
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 confirmed
99.87% purity by HPLC-UV with clean chromatogram showing single major peak at ~12.5 min. High purity is normal for research peptides.
Identity confirmed by LC-MS
Mass spectrum shows expected Tesamorelin molecular ion peaks with appropriate charge states.
Endotoxin testing performed
LAL assay per USP <85> with two replicates both passing at ≤0.05 EU/mL sensitivity.
Lot number present
TESM-052026-4 clearly stated with accession number 2605130118.
Dates within normal range
Received 2026-05-13, reported 2026-05-14 (1-day turnaround). Both dates are before today (2026-09-05).
Lab verification unclear
Freedom Diagnostics Testing website and contact provided, but independent verification of lab accreditation/credentials not possible from document alone. No ISO/GMP certification marks visible.
Limited panel scope
Heavy metals, microbial contamination, sterility, and residual solvents/water content not tested. This is common for basic research-grade COAs but limits comprehensive quality assessment.
Professional presentation
Document includes logo, chromatogram, mass spectrum, signature, QR code, and appropriate research-use-only disclaimers.
