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).
1.00 RT match, 1000 spectral match
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.823%, 99.772%, 99.986%
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 across three vials
Three vials tested with purity values of 99.823%, 99.772%, and 99.986%. This is normal for research-grade peptides and indicates good manufacturing quality.
Identity confirmed by dual methods
TB-500 identity verified by both retention time (RT) match (1.00) and spectral match (1000) across all three samples, indicating proper compound identification.
Batch/lot number present
Client SID TB202601 clearly documented.
Sample date not specified
COA shows publication date (2026-01-14) but does not explicitly state when the sample was received or initially tested.
Lab information complete
TrustPointe Analytics LLC with full address (1743 142nd Ave Suite 4, Dorr, MI 49323), phone (616-359-9023), website, and verification URL provided.
Limited testing scope
Only identity and purity panels performed. No heavy metals, microbial, endotoxin, sterility, or residual solvent testing. This is common for basic research peptide testing but limits comprehensive safety assessment.
Professional presentation
Document includes QR code for verification, dual signatures (Ashlee Lust, President; Joshua Lust, Managing Director), and photo attachment of tested vials. System suitability (0.7% RSD) and coelution control (999) documented.
