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)
- 98.7%
Scored lower because the document is mostly consistent but carries soft concerns, limited panel coverage (3/7), 4 soft concerns, and notable note: "High purity achieved". To improve: include identity, purity, and endotoxin at minimum and prefer labs with a public verification portal.

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).
Conform
Purity
Tested · passed · core
Reported purity percentage for the analyte.
98.7%
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
Tested · passed
Residual solvents or water content limits.
5.8% water, 6.0% acetic acid
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 achieved
98.7% peptide purity by HPLC with total impurities 1.3% and largest single impurity 0.9%, all within specifications
Identity confirmed
Appearance and solubility conform to specifications; HPLC identity testing performed
No laboratory identification
Document does not identify the testing laboratory name, address, accreditation, or contact information
No verification mechanism
No URL, QR code, or other method provided to independently verify this COA with the issuing laboratory
Limited testing scope
This COA covers purity and identity testing only. No heavy metals, microbial, endotoxin, or sterility testing is documented on this report
Batch information present
Batch number 2023052401-1, production date 2023/07/10, survey date 2023/07/31
Dates are consistent
Production date (2023-07-10) precedes survey date (2023-07-31); retest date (2025-07-09) is approximately 2 years from production
Generic formatting
Document uses basic table layout without laboratory branding, letterhead, or distinctive formatting that would aid verification
Timing & next steps
Practical follow-ups based on document age and gaps.
coa age
This COA was issued over a year ago (1132 days) — consider whether a retest is warranted for this batch.
