No formulation disclosure is required for the Essentials Plan. For Mechanism of Action or Ingredient Interaction studies of the Investigator and Opinion Leader Plan, disclosure of formulation is required.

No. All our testing is in-vitro — conducted on cell models in a laboratory setting. No live animals are used at any stage.

We help you re-scope to a claim your formulation does support.

Yes. We can co-run multiple SKUs, contact us for bulk pricing with the "Check Pricing" form above.

Yes. The test report we provide includes the methodology, cell models used, and quantified biological outcomes. It is written to be scientifically legible — meaning a veterinarian can read it, evaluate it, and explain the mechanism to a client or colleague. It is not a marketing summary. It is a scientific document.

It is the most important starting point. Vets are trained to ask 'how do you know this?' If your answer is 'our supplier says so' or 'it's on the label,' the conversation ends. A validated claim with a test report gives you a credible, specific answer to that question — in terms a vet recognizes.

EU: Under EU Regulation (EC) No 767/2009, Article 13(1)(b), health claims on pet food must be backed by scientific evidence — available before the product goes to market, not after a challenge arrives. The FEDIAF Code of Good Labelling Practice confirms that in-house and proprietary data counts. An in-vitro biological study on your finished formulation is valid substantiation under this framework.

UK: The principles of the EU feed regulations were retained in UK domestic law after Brexit. The FSA is responsible for controlling claims and the implementation of safety measures. The substantiation standard is the same: scientific evidence, available on request, before market entry.

US: The FDA, AAFCO model regulations, and FTC truth-in-advertising standard all require the same thing: claims must be truthful and supported by competent scientific evidence. In-vitro biological data on finished formulations is accepted as part of a substantiation package for functional and structure/function claims.

A clinical trial tells you whether a product works. A lab study runs first, for a fraction of the cost, and it also shows why — which ingredient does the work, at what dose, and whether the parts of your formulation interfere. Lab first, trial second: the lab result tells you whether the trial is worth running. It does not replace the trial.
