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.
1 of 7 present · 0 passed · 0 failed · 1 reported · 6 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
Not on this COA · core
Compound identity confirmed (e.g. HPLC, mass spec).
No evidence for this panel. That lowers thoroughness — whether it matters depends on what you care about.
Purity
Tested · result on file · core
Reported purity percentage for the analyte.
99.163%; 99.169%; 99.086%
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 reported
Three measurements averaging ~99.14% purity for Semaglutide, consistent with high-quality research peptide standards
No identity confirmation method stated
Report does not specify the analytical method used for identity confirmation (e.g., MS, NMR). Only purity values and mass measurements are provided.
Batch number present
Batch SEM10N032525 clearly stated
Dates are consistent and valid
Testing ordered 29 MAR 2025, sample received 02 APR 2025, analysis conducted 03 APR 2025. All dates are sequential and within normal timeframes, and all are on or before 2026-07-29.
Known testing laboratory
Janoshik Analytical is a recognized third-party peptide testing laboratory with established reputation in the research peptide community
Verification system provided
Document includes verification URL (www.janoshik.com/verify/) and unique key (2NZTZXKG4741) for authentication
Limited testing scope
Only purity testing performed. No identity confirmation method stated, no heavy metals, microbial, endotoxin, sterility, or residual solvent testing. This is common for basic peptide purity assessments but limits comprehensive quality assurance.
Professional presentation
Document follows standard Janoshik format with clear sections, QR code, signature, and verification information
Timing & next steps
Practical follow-ups based on document age and gaps.
