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).
FTIR sample spectrum confirms the presence of Retatrutide with addition of excipient(s)/fillers
Purity
Tested · passed · core
Reported purity percentage for the analyte.
99.6%
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
HPLC purity of 99.6% meets specification (≥98%) and is within normal range for research-grade peptides
Identity confirmed by dual methods
Both FTIR and HPLC methods confirm Retatrutide identity with appropriate excipients present
Complete batch traceability
Lot number WL-RT10-P00521 and BT Sample ID 005000040403782 provided
Dates are current and logical
Date tested (2026-06-08) precedes issue date (2026-06-12) by 4 days, both are before today (2026-07-29)
Established testing laboratory
BTLabs (West Palm Beach, FL) with complete contact information and dual scientist signatures
Limited testing scope
COA explicitly states it does not provide information on particulate matter, microbial contamination, or endotoxins. Heavy metals and sterility testing also absent.
Professional presentation
Well-formatted 2-page report with QR code, chromatograms, FTIR spectrum, USP method references, and dual signatures
