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).
ID Confirmed
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
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 chromatographic purity
HPLC-UV/MS shows >99.9% purity with clean chromatogram showing single dominant peak at ~7 minutes retention time
Mass spectral confirmation
Mass spectrum provided showing expected m/z peaks for Tirzepatide (1614.3, 1605.9 major ions), ID confirmed by comparison to authentic standard
Batch/lot number present
Batch psgpwr8 clearly identified with vial photograph
Dates within normal range
Sample received 2026-05-28, tested 2026-06-02, report issued 2026-06-05 - all dates are sequential and reasonable
Established laboratory
Krause Analytical LLC is a known third-party testing laboratory in Austin, TX. Document includes verification URL and lab director signature
Limited testing panels
Only identity and purity testing performed. Methods summary describes endotoxin and metals testing procedures but no results are shown for these panels
Professional presentation
Multi-page report with chromatogram, mass spectrum, detailed methods summary, and proper laboratory branding. Includes USP/NF method references
Potency vs label claim
7.88 mg recovered vs 10 mg label claim = 78.8% of label, which is within acceptable range for lyophilized peptides accounting for moisture and counterions
