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 (Retatrutide)
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.62%
Heavy metals
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
As: 0.335 ppm, Cd: 0.1006 ppm, Pb: 0.1005 ppm, Hg: 0.1087 ppm, Cr: 0.1387 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.
NMT 0.05 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 with conformity testing
99.62% purity (batch mean 99.43%, std dev 0.1349%) across 3 conformity samples. HPLC chromatogram shows clean single peak. This is normal for research-grade peptides.
Identity confirmed by HPLC-RTM
Compound confirmed as Retatrutide (GLP-3 RT) by retention time comparison with reference standard.
Batch information complete
Lot RT10-655, COA-2026-R9UV-W, Accession ACC-2026-6114. Net peptide content 10.55 mg (labeled 10 mg).
ISO/IEC 17025 accredited lab
ILS Laboratories, San Diego CA. ISO/IEC 17025 accredited. Verification URL and access code provided. Lab director signature present.
Comprehensive testing suite
Five panels present: purity (HPLC), identity (HPLC-RTM), heavy metals (ICP-MS), sterility (PCR), endotoxin (USP <85>). All tests passed. Microbial culture and residual solvent/water panels not included.
Professional presentation
Two-page format with detailed methodology notes, conformity testing data, QR code for verification, and proper accreditation disclaimers. Formatting is consistent with professional analytical lab standards.
