Science-Backed Testing You Can Trust
We use advanced laboratory methods to find out what's really in your products — because brands won't tell you, and you deserve to know.
Our Core Principles
These principles guide every test we conduct.
$0 From Brands
We never accept money, free products, or sponsorships from the companies we review. Our only funding comes from members like you.
We Buy Everything
Every product is purchased from real retail stores — Amazon, Walmart, Target, or direct from websites. Never sent by manufacturers.
Third-Party Labs
All testing is conducted by independent, accredited laboratories. We never test products ourselves to avoid bias.
Our Testing Methods
We employ 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 harmful bacteria, mold, and other pathogens that could pose health risks.
- 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
Our 6-Step Testing Process
From purchase to publication, here's how we review every product.
Product Selection
We identify popular products through sales data, member requests, and safety concerns. Priority goes to products with the most consumer impact.
Anonymous Purchase
We buy products from real retail channels — never from manufacturers. This ensures we test the same products you'd actually buy.
Lab Submission
Products are sent to accredited third-party laboratories with chain-of-custody documentation. We never handle samples ourselves.
Analysis & Testing
Labs perform comprehensive testing using mass spectrometry, microbial analysis, and other methods appropriate for the product category.
Expert Review
Our team of scientists reviews the raw lab data, interprets the results, and assigns scores based on our transparent scoring criteria.
Publication
Results are published with full transparency. Members get access to detailed lab reports, not just summary scores.
How We Score Products
Our scoring system is transparent and consistent across all products.
Excellent
Exceptional quality with no significant issues
Very Good
High quality with minor concerns
Good
Solid product with some room for improvement
Fair
Acceptable but notable issues present
Poor
Significant concerns that consumers should consider
Not Recommended
Serious issues — we cannot recommend this product
Scoring Factors
Purity
Absence of contaminants and unwanted substances
Label Accuracy
Does the product contain what it claims?
Safety
Heavy metals, pathogens, and other safety concerns
Value
Quality relative to price point
Accredited Laboratory Partners
We work exclusively with ISO 17025 accredited laboratories to ensure the highest standards of accuracy and reliability.
