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.
5 of 7 present · 5 passed · 0 failed · 0 reported · 2 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).
Confirmed (Tesamorelin)
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.78%
Heavy metals
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
As: 0.11 ppm, Cd: 0.109 ppm, Pb: 0.322 ppm, Hg: 0.437 ppm, Cr: 0.889 ppm
Microbial
Not on this COA
Bioburden / microbial limits testing.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Endotoxin
Tested · passed · core
LAL or chromogenic endotoxin assay.
0.2 EU/mL
Sterility
Tested · passed
Sterility testing where applicable.
No Growth
Residual solvent / water
Not on this COA
Residual solvents or water content limits.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
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
Not on this certificate. Lowers thoroughness; you decide if that panel matters for your use case. PeptIQ’s score still factors coverage.
Findings
Evidence-linked observations from this audit.
High purity confirmed
99.78% purity by HPLC with conformity testing across 3 samples (mean 99.75%, std dev 0.0189%). This is normal for research-grade peptides.
Identity confirmed
Tesamorelin confirmed by HPLC retention time match with reference standard. Includes fentanyl screen (not detected).

Lab credentials present
ILS Laboratories, San Diego CA. ISO/IEC 17025 accredited. Signed by Dr. Greg Kalyuzhny, Lab Director. Verification URL and QR code provided.
Comprehensive testing
Five panels present: identity, purity, heavy metals, endotoxin, sterility. All passed. Microbial culture and residual solvents not tested (common for peptide COAs).
HPLC chromatogram included
Representative chromatogram shown for Dedicated V0 sample (99.74% purity). Clean peak profile consistent with high-purity peptide.
Cannot independently verify lab
ILS Laboratories is not widely known in public databases. Verification URL provided but cannot be tested in this audit context. This is noted but does not constitute evidence of fabrication.
