Independence Index
How much of a vendor's published test evidence is its own. A count of certificates is not a count of tests: when one laboratory result is issued under several vendor names, every one of those names appears to hold evidence that only one test produced.

Definition. A certificate is counted as not independent when its
measurement fingerprint — testing lab, compound, purity%, content in mg, and test date —
is shared with at least one certificate carrying a different vendor name. Batch numbers are excluded
from the fingerprint, because vendors assign them independently. Certificates whose purity or content
is zero or unreadable are excluded, because an absent measurement is not a match. The testing lab is
part of the fingerprint, so identical readings from two different labs count as two tests rather than
one resold test.
What this measures, and what it does not. It measures how much of the evidence published under a vendor's name was produced by a test that vendor does not exclusively hold. It is not a purity measure, not a quality score, and not a finding of wrongdoing. There are ordinary reasons a fingerprint is shared: a single manufacturer selling under several brand names, one distributor supplying several storefronts, or a laboratory reissuing one result to multiple clients — a practice some labs mark openly on the certificate itself. This page applies the same test to every lab and does not treat one as worse than another.
Nothing here establishes who produced any material, and nothing here should be read as an allegation against any named party. Every underlying case, with its certificates and lab verification links, is on the duplicate detection page.

Limits of this page. Coverage is bounded by what has been read into the corpus, so
every figure here is a floor rather than a census. A vendor absent from this table has no detected
shared test — which is not the same as proof that every certificate it publishes is independent.
Detection also depends on the measurements being legible: a certificate with unreadable purity or
content cannot be matched to anything. Where a laboratory reissues a result and gives the copy an
unrelated certificate number, the link is invisible from outside and surfaces only when the underlying
measurements are compared — so labs that mark reissues openly will tend to appear more often here
than labs that do not, and that is an artefact of documentation practice, not of conduct.
Vendors identified only by an email address are excluded from this table.
