Methodology

How We Test

We buy the products, run them through millions of dollars of lab equipment, check for anything that shouldn't be there, and report the results to you.

Two labs. Zero bias.

Every product is tested in our in-house lab, then independently confirmed by a second accredited lab before anything goes public.

Our testing steps

1

We buy the products

We buy products at retail — the same stuff you'd find at Target or Walgreens. No brand samples, no PR kits.

2

We test beyond where others stop

We use the most advanced lab equipment available — mass spectrometers, FTIR, DNA sequencing — and keep looking long after most would call it done.

3

We make the science simple

We turn everything the lab finds into something you can actually use — so you know which products are healthiest for you and your family.

4

We confirm with a second lab

Every primary finding is verified by an independent, accredited lab before anything gets published.

5

We publish with full transparency

We only publish once both labs agree — with full context on what we found, what we didn't, and where the limits are.

Detection limits

What we can reliably measure — and the instruments that do it.

Our Approach: Radical Transparency, Not Certification

What This IS:. A sensitive screening tool that identifies volatile chemicals "off-gassing" from the product using Headspace Gas Chromatography-Mass Spectrometry (GC/MS).

What This is NOT:. A regulatory compliance test. We do not quantify non-volatile ingredients or heavy metals in this screening. We do not certify products as "safe" or "unsafe."

For educational and informational purposes only. Not medical advice. Consult qualified professionals for health decisions.

How We Test

Two labs. Zero bias.

Every product moves through our in-house lab, then an independent accredited partner. Both labs have to agree before any finding goes public.

Step inside the labBrowse all categories

The Investment

Built in-house. Run by us.

Millions of dollars of analytical instrumentation sits behind our primary screening — not an outsourced black box.

Capital

Millions Invested

Our lab is built on millions of dollars of analytical instrumentation so we can run primary tests ourselves, not outsource the core work.

Identification

Mass Spec & HPLC

High-resolution mass spectrometers and HPLC systems quantify trace contaminants and verify label claims with precision.

Composition

Gamma-Ray & Microbial

Gamma-ray spectroscopy and microbial analysis detect elemental composition, contaminants, and pathogens across product categories.

Lab milestones

From mass-spec to publication.

Every product walks the same path. No narrative until both labs agree on the numbers.

  1. 01

    ShopKeeper’s shelf

    Anonymous retail purchase

    We buy products from real retail channels so the samples match what consumers actually receive.

  2. 02

    TPR intake bench

    Chain-of-custody intake

    Every sample is logged, photographed, and sealed under clean-room procedures. Two techs sign off.

  3. 03

    Mass Spec · HPLC

    Primary screening

    Mass spectrometry (QTOF, LC-MS, GC-MS) identifies compounds at parts-per-billion. HPLC quantifies label claims.

  4. 04

    Partner lab

    Level 2 confirmation

    Samples go to an independent, accredited Level 2 lab that verifies every primary finding before anything is published.

  5. 05

    Data review

    Cross-verification

    Both result sets have to align before any conclusion is accepted. Disagreement means a second run, not a shipped story.

  6. 06

    TPR Scoring

    Expert scoring & review

    Our scientists interpret the data and apply the transparent TPR Score rubric before the report is drafted.

  7. 07

    Public report

    Publication with full data

    The report goes public once both labs agree, with charts that link back to the raw chromatograms.

Integrity

Scientific rigor

Most testing services use a single lab. We use two. Our in-house analysis is independently confirmed before anything goes live.

Defensibility

Harder to dismiss

Any brand that challenges our results has to dispute two independent analyses. That makes our findings harder to dismiss and safer to publish.

Instrumentation

What we run. What it finds.

Laboratory-grade analytical techniques that go far beyond what brands claim on their labels.

Mass Spectrometry

Identifies and quantifies compounds at parts-per-billion levels. Detects heavy metals, pesticides, and unknown contaminants.

  • ICP-MS for heavy metals
  • LC-MS for organic compounds
  • GC-MS for volatiles

Gamma-Ray Spectroscopy

Measures radioactive isotopes and elemental composition without destroying the sample.

  • Detects trace elements
  • Non-destructive testing
  • Identifies contamination sources

Microbial Analysis

Tests for bacteria, mold, and other microorganisms of regulatory concern.

  • Total plate count
  • Yeast & mold
  • Pathogen screening (E. coli, Salmonella)

Nutritional Verification

Verifies label claims by measuring actual nutrient content against what brands advertise.

  • Protein content analysis
  • Vitamin & mineral levels
  • Calorie verification

TPR Score

How the score is built.

The TPR Score starts at 100. Deductions are applied in three tiers, then category-specific weighting is applied. This is a screening intelligence framework, not a regulatory decision.

90–100

Minimal findings

Product aligns with label claims.

70–89

Some findings

Some findings detected. Review details.

50–69

Multiple findings

Multiple findings or significant concerns detected.

< 50

Major findings

Regulatory thresholds may be exceeded.

Important disclosures

Our Approach: Radical Transparency, Not Certification

We believe in showing you the data, the limitations, and letting you make informed decisions.

What This IS:

A sensitive screening tool that identifies volatile chemicals "off-gassing" from the product using Headspace Gas Chromatography-Mass Spectrometry (GC/MS).

What This is NOT:

A regulatory compliance test. We do not quantify non-volatile ingredients or heavy metals in this screening. We do not certify products as "safe" or "unsafe."

The 'Black Box' Disclaimer:

We rely on NIST Library Matching to identify compounds. While high-probability matches (90%+) are strong indicators, they are not 100% definitive proof of chemical structure without certified reference standards. We publish the raw probability scores so you can decide for yourself.
