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
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.78%
Heavy metals
Tested · passed
Lead, arsenic, cadmium, mercury, or similar limits.
All Not Detected
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.
0.976 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 99.73%, std dev 0.0411%). Consistent results indicate reliable measurement.
Identity confirmed
Melanotan II confirmed by HPLC retention time matching (HPLC-RTM) with reference standard. Chromatogram shows clean single peak.
Comprehensive testing panel
Full QC panel includes purity, identity, heavy metals (ICP-MS), sterility (PCR), endotoxin (USP <85>), and fentanyl screening. All tests passed.
Batch information complete
Lot number CR-MT2-10-2605-1, COA number COA-2026-73RMCX, Accession ACC-2026-3077. Net peptide content 10.71 mg (labeled 10mg).
Timeline appropriate
Sample received 2026-05-22, analyzed 2026-06-01, issued 2026-06-01. 10-day turnaround is reasonable for full panel testing.
ISO/IEC 17025 accredited lab
ILS Laboratories, San Diego, CA. ISO/IEC 17025 accredited. Includes verification URL, QR code, and access code (7DWZNLVU) for authentication.
Professional presentation
Well-formatted 2-page COA with clear tables, chromatogram, methodology notes, and lab director signature. Includes conformity testing data showing batch consistency.
Microbial and residual solvent panels absent
No microbial contamination testing (beyond sterility PCR) or residual solvent/water content analysis. Not uncommon for research-grade peptides but worth noting.
