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).

    FTIR sample spectrum confirms the presence of Selank with addition of excipient(s)/fillers

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.9%

  • 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.

    20.7 EU/vial (limit: 40 EU/vial)

  • 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 HPLC purity achieved

    99.9% purity by HPLC (USP <621>) meets specification of ≥98%. This is normal for research-grade peptides.

  • Identity confirmed by FTIR

    FTIR spectrum confirms presence of Selank with excipients/fillers, consistent with formulated peptide product.

  • Potency values show high variability

    Three potency measurements show 93.6%, 101.6%, and 136% of labeled 10mg. The 136% value exceeds the 90-110% specification range, indicating potential sample heterogeneity or measurement inconsistency.

  • Endotoxin testing passed

    Bacterial endotoxin test (separate report dated 4/10/2026) shows 20.7 EU/vial, well below the 40 EU/vial limit.

  • Batch and sample IDs present

    Lot number CR-SLNK10-2603-1 and BT Sample IDs (005000039491462, 005000039491594) are clearly documented.

  • Dates are consistent and valid

    Sample tested 4/2/2026, report issued 4/5/2026; endotoxin test dated 4/8/2026, report 4/10/2026. All dates are sequential and on or before 2026-07-28.

  • Lab verification not independently confirmed

    BTLabs (West Palm Beach, FL) contact information and website provided, but independent verification of lab accreditation or registration status not performed within this audit.

  • Professional formatting with supporting data

    Report includes FTIR spectrum, HPLC chromatogram, detailed mass measurements, peptide-to-excipient ratios, and dual scientist signatures. Formatting appears consistent with legitimate analytical lab reports.

  • Limited scope of testing

    Testing purpose explicitly states it does NOT provide information on particulate matter, microbial contamination (beyond endotoxins), or sterility. Heavy metals and residual solvents not tested.
