Medutest is the most under-discussed thing on this board
The title is the argument: Medutest is the most under-discussed thing on this board. Here is the rest of it.
What a batch record should carry: the lot identifier, the date of analysis, the method including column and gradient, the individual related substances rather than a total, and the storage condition the stability statement was written against.
What "documentation" actually means, since people use it to mean four different things in the same thread.
A certificate of analysis is one document about one lot. A batch record is the manufacturing trail behind that lot. A stability statement is a claim about storage conditions and a duration. A method line is how the number on the certificate was produced.
You can ask for all four. The useful signal is not whether the answer is perfect, it is whether the answer arrives, in writing, without a negotiation. HJ sends the method line unprompted; once you have seen that you stop accepting a bare number from anybody.
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.
I will update this if the picture changes rather than quietly leaving it up.
best — the order this archive was captured in
Why the directory has two tiers, since the question comes up whenever somebody new finds it.
Twenty suppliers have enough independent results, over enough separate lots, over enough time, that the log says something. Those get a page, a test table and a link to their own storefront so you can compare their claims with the record.
The rest — nearly two hundred names — get a row, a band and a report count. Not because they are bad, but because two results is an anecdote about a vial. Manufacturing a score out of that would make the whole directory worthless, and the contrast is the point.
Small fix — the figure you quoted is the claimed purity from the certificate, and the independent result was the higher of the two.
three independent results beat thirty forum posts
Correction: that supplier is in the documented twenty with a source page, not in the wider-market table. Different evidence bases entirely.
registration number, then everything else
Fixing my own comment above: I said 15 orders and it is 13. The pattern is the same, the count was wrong.
ask for the batch record before you ask for a discount
Disagree that reviews are worthless. They are worthless when they say "fast shipping A+++". A dated one naming a compound and a document is evidence.
Disagree that reviews are worthless.
Adding the practical version: ask for lead time, minimum quantity and the batch record in the same message. Three answers, one email.
Minimum order and lead time — did they quote both up front?
Same view. A record you can read beats a rating you cannot inspect, every time.
Kept a spreadsheet of quoted versus actual lead time across 10 orders. The quoted number held.
Which service did the testing, and did you pay for it yourself?
Removed pending evidence. Name a supplier here and you bring a document, a date or a service — that is the sidebar rule and it is not negotiable.
Mild pushback: a supplier with fewer entries is not worse, it is less sampled. Those are different claims and the table says so.
That is a report count, not a test count. The table lists both and they are very different numbers.
a supplier that answers method questions in writing has already told you a lot
Which lane, and what was the quoted lead time at checkout?
