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
- 68
- Confidence
- 82%
- Panels
- 3/7
- Purity (printed)
- 71.61%
Scored lower because the document is mostly consistent but carries soft concerns, limited panel coverage (3/7), 5 soft concerns, and notable note: "Low chromatographic purity". 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 · 1 passed · 0 failed · 2 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).
ID Confirmed
Purity
Tested · result on file · core
Reported purity percentage for the analyte.
71.61%
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 · result on file · core
LAL or chromogenic endotoxin assay.
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.
Low chromatographic purity
71.61% purity is below typical research-grade peptide standards (usually ≥95%). This indicates significant impurities.
Low peptide mass recovery
Total peptide mass is 3.80 mg in a 5 mg vial (76.1% of label claim), indicating underfill or degradation.
Identity confirmed
Mass spectrum matches Tesamorelin reference standard with appropriate m/z peaks (644, 735).
Incomplete testing scope
This report shows only purity/identity analysis. Methods summary describes endotoxin (LAL) and heavy metals (ICP-MS) testing procedures, but no results are provided in this document. This may be a purity-scoped report only.
Vendor/lab name inconsistency
Document header shows 'Finnrick Analytics' and 'Finnrick.com' but footer and signature reference 'Krause Analytical LLC'. This dual branding suggests Finnrick may be a reseller/distributor using Krause as the testing lab.
Watermark and formatting anomalies
Heavy 'FINNRICK' watermark throughout document and page numbering inconsistencies ('Page 1 of 23' vs 'Page 1 of 3') suggest possible template reuse or document assembly issues.
Batch/lot number present
Lot number k6fsnyx is clearly stated and matches verification ID.
