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).

    SLU-PP-332

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.98%

  • 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 confirmed

    99.98% purity by LC-MS with supporting chromatogram showing single dominant peak at retention time 0.70 min

  • Identity confirmed

    Compound identity verified as SLU-PP-332 with CAS 303760-60-3, molecular formula C18H14N2O2, molecular weight 290.3 g/mol. PubChem CID 5338394 reference provided

  • Batch information present

    Batch/Lot number SHRED-0001 clearly stated

  • Dates within normal range

    Sample received 12/27/24, analysis conducted 1/4/25 - reasonable 8-day turnaround time

  • Lab verification uncertain

    BioRegen presents as independent testing lab with verification URL (bioregen.com/verify) and QR code, but online presence and third-party validation of this specific lab could not be confirmed from document alone

  • Limited testing scope

    Only identity and purity testing performed. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing. This is common for research-grade compounds but limits comprehensive quality assessment

  • Professional presentation

    Document includes proper branding, security key (BIOLABS2010), COA number (#10019), analyst signature (Dr. Roberto Marin), chromatograms, and mass spectrum data

  • Client relationship unclear

    Client listed as 'Biolongevity Labs' - relationship between testing lab (BioRegen) and client requires independent verification to rule out potential conflict of interest

Timing & next steps

Practical follow-ups based on document age and gaps.

  • coa age

    This COA was issued over a year ago (570 days) — consider whether a retest is warranted for this batch.
