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).
GLP-RT confirmed via mass spectrometry with [M+3H]3+ 1577.23, [M+3H+K]4+ 1192.88
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.947%
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.
≤ 0.05 EU/mL (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
99.947% purity by HPLC is within normal range for research-grade peptides and supported by clean chromatogram showing single dominant peak
Mass spectrometry confirmation
Identity confirmed via LCMS/MS with appropriate mass-to-charge ratios for GLP-RT/Retatrutide shown in spectrum
Endotoxin testing included
Endotoxin testing performed in duplicate per USP <85> guidelines, both replicates pass at ≤ 0.05 EU/mL
Batch information present
Lot number 0005 clearly stated, net peptide content 12.62 mg documented
Dates within normal range
Received 2025-11-19, reported 2025-11-21 (2-day turnaround is reasonable for HPLC/MS testing)
Limited lab verification information
Freedom Diagnostics claims USA operation with searchable verification URL, but no accreditation logos (ISO 17025, GMP, etc.) visible on certificate
Two separate accession numbers for same lot
Page 1 shows accession 2511190035 (purity/identity), page 2 shows 2511190036 (endotoxin) for same product lot 0005. While splitting tests across accessions can be legitimate, this creates potential confusion
Professional but generic template
Document uses clean professional formatting but lacks unique lab-specific design elements or security features common in established testing facilities
Limited testing scope
Only purity, identity, and endotoxin panels present. Missing heavy metals, microbial, sterility, and residual solvent/water testing common in comprehensive COAs
