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).
Melanotan-II confirmed
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.86% (Vial 1: 99.88%, Vial 2: 99.83%)
Heavy metals
Not on this COA
Lead, arsenic, cadmium, mercury, or similar limits.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
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.
Replicate 1: Pass, Replicate 2: Pass
Sterility
Not on this COA
Sterility testing where applicable.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
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
HPLC-UV purity of 99.86% (average of two vials: 99.88% and 99.83%) is within normal range for research-grade peptides
Identity confirmed by LC-MS
Mass spectrometry confirmation provided with chromatogram showing single peak at ~10 minutes retention time
Endotoxin testing included
LAL assay performed per USP <85> with sensitivity ≤0.05 EU/mL, both replicates passed
Batch information present
Lot number MT2-052026-1, accession number 2605210564, search code provided
Dates within normal range
Received 2026-05-21, reported 2026-05-23 (2-day turnaround)
Lab verification uncertain
Freedom Diagnostics Testing website and contact information provided, but independent verification of lab accreditation/credentials not possible from document alone
Limited testing panel
Heavy metals, microbial contamination, sterility, and residual solvents/water content not tested. This is common for basic peptide COAs but limits comprehensive quality assessment
Professional presentation
Document includes logo, signature, QR code, chromatogram, mass spectrum, and appropriate disclaimers for research use only
