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.
2 of 7 present · 2 passed · 0 failed · 0 reported · 5 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).
PT-141 confirmed, MS peak at 1025 m/z
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.36%
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
Not on this COA · core
LAL or chromogenic endotoxin assay.
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
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
99.36% purity by UPLC is excellent and typical for research-grade peptides. Clean chromatogram with single dominant peak.
Identity confirmed by MS
Mass spectrometry shows expected molecular ion peak at 1025 m/z, consistent with PT-141 (bremelanotide) molecular weight ~1025.2 g/mol. PubChem CID 9941379 referenced.
Clear lot identification
Lot number APR-9495443-P clearly stated and matches across document fields.
Analysis date precedes received date
Analysis conducted 05/17/2026 but sample received 05/22/2026. This is logically inconsistent - analysis cannot occur before sample receipt.
Professional presentation
Document includes lab branding, analyst signature (Aleksey Yevtodiyenko PhD), contact information, and QR code for validation. Professional formatting consistent with analytical lab reports.
Limited testing scope
Only identity and purity testing performed. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing. This is common for basic research-grade COAs but limits safety assurance.
Complete analytical data
Includes both UPLC chromatogram and MS spectrum with clear peak identification. Quantity measured (9.75mg vs 10mg specification) is reasonable.
