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.
No ads. No brand influence.Powered by members like you.
Methodology
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.
We test retail samples, explain what the sample can and cannot prove, and keep stronger claims behind review.
We buy products at retail — the same stuff you'd find at Target or Walgreens. No brand samples, no PR kits.
We use the most advanced lab equipment available — mass spectrometers, FTIR, DNA sequencing — and keep looking long after most would call it done.
We turn lab and label evidence into practical context — what stood out, what did not, and what still needs review.
Primary findings can be confirmed by an independent, accredited lab before stronger public claims are made.
We publish with context on what we found, what we didn't find, and where the limits are.
What we can reliably measure — and the instruments that do it.

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."

How We Test
We test retail samples, explain what the sample can and cannot prove, and keep stronger claims behind review.
The Investment
Millions of dollars of analytical instrumentation sits behind our primary screening — not an outsourced black box.
Capital
Our lab is built on millions of dollars of analytical instrumentation so we can run primary tests ourselves, not outsource the core work.
Identification
High-resolution mass spectrometers and HPLC systems quantify trace contaminants and verify label claims with precision.
Composition
Elemental analysis and microbial testing screen for heavy metals, contaminants, and pathogens across product categories.
Lab milestones
Every product walks the same path. No strong claim until the evidence and limits are clear.
ShopKeeper’s shelf
We buy products from real retail channels so the samples match what consumers actually receive.
TPR intake bench
Every sample is logged, photographed, and sealed under clean-room procedures. Two techs sign off.
Mass Spec · HPLC
Mass spectrometry (QTOF, LC-MS, GC-MS) identifies compounds at parts-per-billion. HPLC quantifies label claims.
Partner lab
Higher-risk primary findings can go to an independent, accredited Level 2 lab before stronger public claims are made.
Data review
When result sets do not align, the answer is more review or another run, not a stronger story.
TPR Scoring
Our scientists interpret the data and apply the transparent TPR Score rubric before the report is drafted.
Public report
The report goes public when review evidence is complete, with charts that link back to the raw chromatograms where available.
Integrity
Most testing services use a single lab. We use two. Our in-house analysis is independently confirmed before anything goes live.
Defensibility
Any brand that challenges our results has to dispute two independent analyses. That makes our findings harder to dismiss and safer to publish.
Instrumentation
Laboratory-grade analytical techniques that go far beyond what brands claim on their labels.
Identifies and quantifies compounds at parts-per-billion levels. Detects heavy metals, pesticides, and unknown contaminants.
Separates and quantifies individual compounds in complex product formulations.
Tests for bacteria, mold, and other microorganisms of regulatory concern.
Verifies label claims by measuring actual nutrient content against what brands advertise.
TPR Score
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, medical recommendation, or blanket brand judgment.
Minimal findings
Product aligns with label claims.
Some findings
Some findings detected. Review details.
Multiple findings
Multiple findings or significant concerns detected.
Major findings
Regulatory thresholds may be exceeded.
| Tier | Point range | Examples | Description |
|---|---|---|---|
| Tier 1 | -30 to -50 | Benzene, 1,3-Butadiene, Formaldehyde | Known hazardous compounds with the highest deduction weight. |
| Tier 2 | -15 to -25 | Phthalates, 1,4-Dioxane, Heavy Metals | Compounds of concern with moderate-to-high deduction impact. |
| Tier 3 | -5 to -15 | Label Mismatch, Degradation Products, QC Flags | Quality and transparency indicators used for comparative context. |

Important disclosures
We believe in showing you the data, the limitations, and letting you make informed decisions.
A sensitive screening tool that identifies volatile chemicals "off-gassing" from the product using Headspace Gas Chromatography-Mass Spectrometry (GC/MS).
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."
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.
