Bust a fake — and you could get rewarded
Reporting an adulterated or fraudulent supplement can qualify for federal and state whistleblower programs. An independent, lab-grade TestMySupps report is exactly the kind of documented evidence those programs rely on — so catching a fake could even pay you back.
Eligibility and any reward are determined solely by the relevant government program. We provide the analysis — not legal advice.

Turnaround
Liquid Chromatography–Tandem Mass Spectrometry
Separates a sample into its individual compounds and then weighs each one at the molecular level. Used to confirm a specific active ingredient is truly present and to detect hidden or undeclared drugs.
High-Performance Liquid Chromatography
A workhorse method that measures exactly how much of an active ingredient is in a product. Used to verify potency against the label claim.
Inductively Coupled Plasma Mass Spectrometry
An extremely sensitive technique for detecting trace metals. Used to screen for heavy-metal contaminants such as lead, arsenic, cadmium and mercury.
Gas Chromatography–Mass Spectrometry
Identifies volatile compounds and solvent residues. Used to spot adulterants and unexpected substances that shouldn't be in a supplement.
Fourier-Transform Infrared Spectroscopy
Reads the molecular 'fingerprint' of a material. Used for fast identity checks and to flag fillers or substituted ingredients.
Chromatography Columns & Reference Standards
The precise separation media and certified reference materials our instruments rely on — so every measurement is compared against a known, traceable standard.
We select the method best suited to each supplement. We report measured values only and make no health claims — we are a testing service, not a medical provider.
Real people, real discoveries
I tested two testosterone boosters I'd been taking for months. One had barely a third of what the label claimed. Worth every penny to finally know.

I honestly didn't expect this — my weight-loss drops came back as not what the label said. I'd suspected it for weeks. So relieved I finally checked. Thank you TestMySupps!

Sent in a GLP-1 supplement I was unsure about. The peptide analysis gave me real answers in under two weeks. So thankful I didn't keep taking it blind.

Clear, professional report with actual measured numbers. No marketing, no fluff — exactly what an independent test should be.
Dana R.

With so many supplement companies and basically no regulation, this finally gave me peace of mind. My multivitamin passed — and now I actually trust it.
Carlos M.
Verified Customer
Surprised and so grateful. I had a bad feeling about a pre-workout I bought online, and the results confirmed it wasn't what it claimed. Money well spent.
