Quality & Testing
Quality should be checked against a specific product and batch, not accepted as a badge. Use this page to understand batch documents and request the document that belongs to your order.
Match the document to your product
A useful quality document identifies what was tested and connects each result to a test, method, unit and date. A report for one ingredient lot, variant or production batch does not automatically describe another.
- Find the batch or lot identifier on your product or packaging.
- Check that the document names the same product and identifier.
- Read what material was tested: ingredient, bulk solution or finished product.
- Review the specification and measured result together.
- Contact us if the match is missing or unclear.
What different documents can tell you
| Evidence | What it supports | What it does not prove alone |
|---|---|---|
| Ingredient specification | The agreed requirements for a named material | That every finished pen meets every requirement |
| Ingredient certificate | Reported results for a particular ingredient lot | Finished-product quality or a health outcome |
| Finished-product report | Named tests on a defined finished batch | Attributes that were not tested |
| Manufacturing certificate | A stated scope for a named site and period | That a specific batch passed every product test |
How to read a result
Look for five things together: the tested item, the test method, the unit, the acceptance criterion and the measured result. A number without its context is easy to misread. A passing result covers only the tests listed in the document.
Our plain-English COA guide explains identity, potency, purity and common certificate limitations.
What a COA does not establish
A certificate of analysis is laboratory evidence within a defined scope. It does not establish a clinical benefit, an individual response, an optimal amount, country-specific legality or equivalence with another product.
- Do not read a missing test as a passing test.
- Do not transfer an ingredient result automatically to the finished product.
- Do not treat a laboratory logo as proof that every method is accredited.
- Do not treat a quality result as a safety or efficacy guarantee for every person.
