Sample Mdrn-Life DDW 0006
The Hydroisotop document directly reports 3.0 ppm for the identified sample and states that the results relate to the measured samples.
Mdrn-Life DDW Laboratory Sample Results
Mdrn-Life publishes available laboratory documents so customers, researchers and practitioners can inspect the evidence behind specific tested samples. Each document should be read according to its sample identification, method, reporting unit and stated uncertainty.
These are sample-specific results. They are not presented as evidence that every Mdrn-Life bottle or every production batch has undergone the same external testing.
Two reports, preserved in the units each laboratory supplied

The USGS document reports δ²H. It does not state a ppm concentration, so Mdrn-Life does not replace the laboratory's unit with an unsupported ppm number.
Different reporting conventions should not be forced into one format
Isotope laboratories may report hydrogen-isotope measurements as δ²H relative to VSMOW. Some reports may also provide a consumer-readable ppm concentration. The two Mdrn-Life documents use different reporting details, and that difference should remain visible.
Transparency rule: show each laboratory result in the unit the laboratory actually reported. Do not create a ppm value where the report does not provide one unless a separate, clearly explained conversion methodology is being presented.
Production target versus measured sample result
5 ppm
Mdrn-Life production target. This is the intended isotope-composition specification for manufacturing.
3.0 ppm
Hydroisotop sample 0006. This is the measured concentration directly reported for that identified sample.
−954.5‰
USGS Field ID 0004. This is the δ²H result reported for that identified sample; no ppm value appears in the document.
These statements are related but not interchangeable. A production target describes what the process is designed to produce; a sample result describes what a particular laboratory measured in a particular submitted sample.
What you can—and cannot—conclude from the reports
You can conclude
The reports provide independent analytical information about the water samples named in the documents. They show the sample identity, the laboratory's reporting method/convention and the values the laboratory issued for those samples.
You should not conclude
That every bottle or every batch has been independently tested, that both laboratories used the same analytical technology, or that an isotope measurement proves any health or treatment outcome.
The report should be inspectable, not reduced to a badge
A phrase such as “lab tested” tells a buyer very little by itself. The original documents let the reader inspect sample identifiers, dates, method/reporting language, values and uncertainty where provided.
That is also why Mdrn-Life separates scientific research from product isotope measurement. A biological study can investigate deuterium without proving the composition of a commercial bottle; a water-isotope report can verify a sample without proving a biological outcome.
