Most brands either skip third-party testing or buy a certification logo without ever showing you the data. We publish the full lab report for every production run.

“Third-party tested” means an independent laboratory — not the brand or its manufacturer — analyzes a finished sample to verify what’s in it and screen for contaminants. But the term is not regulated: a brand can run one basic potency test, or buy a certification logo, and call itself third-party tested. That’s why publishing the results matters more than carrying a badge. Certification tells you a brand paid for a logo; publication tells you what the lab actually found.

Key takeaways

  • “Third-party tested” is not a regulated term — brands with very different rigor can all use it.
  • A serious contaminant panel screens five categories: heavy metals, banned substances, pesticides/herbicides, residual solvents, and microbial contaminants.
  • Most brands that do test still don’t publish results, because publication creates accountability they aren’t ready to accept.
  • Antidote runs a 250+ substance panel across all five categories and publishes the full lab report for every production run, tied to the lot number on the tub.
  • Contamination matters even if you’re not a competing athlete — heavy metals accumulate in the body regardless of why you took the supplement.

When you pick up a tub of supplement powder, there is no practical way for you — the buyer — to know whether what’s printed on the label is actually inside. You take the brand’s word for it. The supplement industry is regulated less rigorously than food and far less than pharmaceuticals, and the gap between “claim” and “verified claim” is wide enough to drive a truck through. That’s the trust problem the whole category lives inside.

What contaminants does a serious test panel cover?

A serious contaminant panel screens for five broad categories. A pre-workout brand that takes testing seriously screens for all five; many don’t.

The five categories in a serious supplement contaminant panel

Category What it is Why it matters
Heavy metals Lead, arsenic, cadmium, mercury Found in commercial powders at levels not permitted in food; accumulate in the body over time
Banned substances Steroids, stimulants, masking agents on the WADA list Usually cross-contamination from shared equipment; a documented cause of failed drug tests
Pesticides & herbicides Residues from the agricultural supply chain Any plant-derived extract was grown on a farm
Residual solvents Hexane, methylene chloride, ethanol from extraction Supposed to be removed from the finished extract — not always
Microbial Bacteria, mold, yeast A manufacturing-hygiene issue, but a real one

What does Antidote test for, and what do we publish?

Antidote runs an independent panel covering more than 250 specific substances across all five categories, and the full lab report for each production run is published on antidote-life.com. You can open it and see exactly what was tested, the detection limits, and what the lab found. No editing, no selective publication, no “results upon request.”

The reason is not complicated. When I was racing, a positive test from a contaminated supplement would have ended my career, and I had no good way to evaluate what I was considering. If we’d had something like Antidote then, the decision would have taken thirty seconds: open the report, read it, decide. That’s the workflow we built the brand around. Here’s the full founder story.

Why don’t most brands publish their results?

Most don’t publish because they either aren’t testing thoroughly in the first place, or they don’t want to disclose what the testing found. There’s a softer reason too: publishing creates a paper trail. A brand that publishes every lot has nowhere to hide if one comes back with an issue; a brand that holds the data internally can quietly reformulate or destroy a problem lot without the public knowing. We chose the harder path on purpose.

Why does this matter if you’re not a competitive athlete?

Contamination doesn’t care whether you’re competing. Heavy metals build up in the body the same way regardless of why you took the supplement. Banned-substance contamination is a marker for sloppy manufacturing — and sloppy manufacturing tends to come with other issues. If you take a pre-workout daily for years, the cumulative exposure is exactly the case to think about hardest.

How to read a supplement test report

A test report lists each substance, the detection limit, the result, and whether it’s within an acceptable threshold set by the methodology — not by the brand. For a clean panel you want to see “Not Detected” or “Below Detection Limit” (ND or <LOD) across the contaminant rows. Tested athletes should focus on the banned-substances panel; consumers thinking about long-term exposure should look at the heavy-metals and pesticides panels first.

Frequently asked questions

Where can I see Antidote’s test results?

The full lab reports for current production runs are published on antidote-life.com. You can open, read, and download them.

Is Antidote Informed Sport or NSF Certified for Sport?

The current production run is not certified by Informed Sport or NSF. Instead we run an independent 250+ substance contaminant panel and publish the full results, because publishing the underlying data is a stronger trust signal than a certification logo without disclosure.

What does the 250+ contaminant panel cover?

Five categories: heavy metals (including lead, arsenic, cadmium, mercury), banned substances on the WADA list, pesticides and herbicides, residual solvents, and microbial contaminants.

Is Antidote safe for a tested athlete to take?

The full banned-substance results are published so you or your compliance officer can review them against your own list before deciding. We provide the data rather than certifying safety on behalf of any sport’s program.

How often is testing run?

Each production run is independently tested, and results are tied to the specific lot number on the tub.

Bottom line

There’s no shortcut to verifying what’s in a supplement — but there is a fast filter: ask to see the test report. Brands that don’t have one, or won’t share it, are telling you something. Antidote publishes the full report for every lot. Read the results, then decide.
