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).
99.896%
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.91% (Vial 1), 99.88% (Vial 2)
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
HPLC purity of 99.896% with dual vial verification (99.91% and 99.88%) is consistent with high-quality research peptide standards
Mass spec confirmation present
Mass spectrometry data shows expected charge states [M+2H+Na]3+ (1584.93) and [M+3H+K]4+ (1193.03), supporting identity verification
Endotoxin testing performed
Duplicate endotoxin testing with passing results (≤ 0.05 EU/mL threshold)
Batch information complete
Lot number CRRT-30-1025-01 clearly stated with dual vial content verification
Dates within normal range
Received 11/6/2025, reported 11/8/2025 - 2-day turnaround is reasonable
Lab identification present
Freedom Diagnostics with searchable URL and contact information provided
Professional presentation
Includes chromatogram, mass spec data, product photos, and proper disclaimer language
Limited testing scope
Heavy metals, microbial, sterility, and residual solvent testing not performed - common for research-grade peptides but limits comprehensive quality assessment
