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).
PT-141
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.67%
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.
Pass (both replicates)
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 99.67% is within normal range for research peptides and supported by clean chromatogram showing single dominant peak
Identity confirmed by LC-MS
Mass spectrometry data provided showing PT-141 molecular ion peaks consistent with bremelanotide structure
Batch information present
Lot number PT10-052026-7 clearly stated with accession number 2605120115
Dates within normal range
Received 2026-05-12, reported 2026-05-14 (2-day turnaround is reasonable)
Lab verification unclear
Freedom Diagnostics Testing website and contact provided, but no independent accreditation numbers (ISO, GMP, etc.) visible on document
Limited testing panel
Only identity, purity, and endotoxin testing performed. No heavy metals, microbial, sterility, or residual solvent testing shown
Generic presentation
Document layout is clean but relatively simple; lacks detailed lab credentials, QA signatures, or chain-of-custody information typical of higher-tier testing facilities
Appropriate disclaimers
Contains standard research-use-only disclaimer and scope limitations appropriate for peptide testing
