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 confirms presence of Retatrutide with excipient(s)/fillers such as mannitol

  • Purity

    Tested · passed · core

    Reported purity percentage for the analyte.

    99.8%

  • 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 HPLC purity

    99.8% purity by HPLC is within normal range for research-grade peptides and meets specification (≥98%)

  • Identity confirmed

    FTIR and HPLC methods used to confirm Retatrutide identity with appropriate USP references

  • Batch information present

    Lot number VKA4ANB clearly stated with BT Sample ID 005000038533543

  • Dates appropriate

    Sample tested 1/22/2026, report issued 1/23/2026 - both dates are valid and sequential

  • Dual branding unclear

    Document shows both BTLabs branding and Finnrick branding with different verification URLs. BTLabs appears to be the testing lab, Finnrick the customer/reseller, but the dual presentation and separate verification URL (finnrick.com/verify) creates ambiguity about chain of custody

  • Limited testing scope

    Document explicitly states it does not provide information on particulate matter, microbial contamination, or endotoxins. No heavy metals, sterility, or residual solvent testing performed

  • Potency specification exceeded

    HPLC potency assay shows 16 mg (106.9%) against specification of 95-105% of 15 mg, which is a minor exceedance of the upper limit

  • Lab contact information provided

    BTLabs contact details include physical address (5730 Corporate Way, Suite 220, West Palm Beach, FL 33407), phone (561-625-0133), email, and website

  • Supporting data included

    FTIR spectrum and HPLC chromatogram provided on page 2 with retention time and area data
