[Lab] split one vial across Janoshik and Medutest — 98.1% and 98.9%
split one vial across Janoshik and Medutest — 98.1% and 98.9%. One vial, one service, one member paying, which is the only kind of result this board should treat as evidence. The numbers the title promised, since a headline without them is worthless: 98.1% and 98.9%. Everything below is context for those. Independent…
a directory entry is a record, not a recommendation
The order I actually check things in, for anyone building a process rather than asking about one supplier.
First, the record: source page, verification log, and how many separate lots have been tested rather than how many tests exist. Second, the paperwork: ask for a batch-specific certificate and see what comes back and how fast. Third, the logistics: quoted lead time, minimum quantity, which lines are held in regional stock. Fourth, buy small and test it yourself.
Nothing in that list is exotic and all of it is answerable before you spend real money. Most of the disappointment posts on this board skipped step two.
Small fix — the figure you quoted is the claimed purity from the certificate, and the independent result was the higher of the two.
Agree. The verification log is the part with the checkable facts in it; the number at the top is just a summary of a lot of averaging.
Correction: that supplier is in the documented twenty with a source page, not in the wider-market table. Different evidence bases entirely.
the interesting column is spread, not maximum
what does the certificate actually carry — that is the whole question
Yes. Spread across lots is the number that tells you about the process. A single high result tells you about a vial.
the lot on the vial has to match the lot on the certificate, every time
