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).
MOTS-C
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.61%
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
99.61% purity by HPLC-UV is excellent and typical for research-grade peptides
Identity confirmed by LC-MS
Mass spectrometry data shows expected MOTS-C molecular ion peaks with fragmentation pattern
Endotoxin testing included
Dual replicate endotoxin testing performed per USP <85> with sensitivity ≤0.05 EU/mL, both replicates passed
Batch information present
Lot number MOTS10-052026-7 clearly stated with accession number 2605120085
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 independent verification of lab accreditation/credentials not possible from document alone
Limited testing scope
Heavy metals, microbial contamination, sterility, and residual solvents/water content not tested - common for basic peptide COAs but limits comprehensive quality assessment
Professional presentation
Document includes chromatogram, mass spec data, clear labeling, and appropriate research-use-only disclaimers
