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.
2 of 7 present · 2 passed · 0 failed · 0 reported · 5 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).
Tesofensine
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.96%
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 achieved
99.96% purity exceeds specification of >98%, consistent with quality research-grade compound
Identity confirmed
Compound identity confirmed as Tesofensine via LC-MS with UV detection, includes PubChem CID reference (11370864)
Quantity variance
Measured quantity 487mcg vs specified 500mcg (-2.6% variance), within typical analytical tolerance but noted
Reasonable timeline
5-day turnaround from sample receipt (03/20/25) to analysis completion (03/25/25) is standard
Lab identification present
BioRegen identified as testing lab with analyst signature (Dr. Roberto Marin), contact information, and verification URL provided
Limited testing scope
Only identity and purity panels performed; no heavy metals, microbial, endotoxin, sterility, or residual solvent testing. Common for basic research compound testing but limits comprehensive safety assessment
Professional presentation
Document includes chromatograms (HPLC and mass spec), QR code for verification, security key, and proper COA formatting with clear specifications vs results table
Timing & next steps
Practical follow-ups based on document age and gaps.
coa age
This COA was issued over a year ago (490 days) — consider whether a retest is warranted for this batch.
