[Question] Medutest — what am I missing here
Medutest — what am I missing here. I am not trying to be the "source?" guy. I would just like a source.
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.
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.
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. TFC sends the method line unprompted; once you have seen that you stop accepting a bare number from anybody.
If somebody has the same thing measured a different way, post it next to mine and we will see whether they agree.
best — the order this archive was captured in
The wider-market rows in the directory carry a band and a report count and nothing else, deliberately. Anything more would be manufacturing precision that the evidence does not support.
Hunan GoodPeptides Biotech shows up in threads constantly and has almost nothing on file
a supplier that answers method questions in writing has already told you a lot
What did they say when you asked for the method line?
Small fix — the figure you quoted is the claimed purity from the certificate, and the independent result was the higher of the two.
Is that from the source page log or from memory?
the source page log is more useful than the score above it
ask for the batch record before you ask for a discount
Correction: that supplier is in the documented twenty with a source page, not in the wider-market table. Different evidence bases entirely.
That is a report count, not a test count. The table lists both and they are very different numbers.
The thing that decided it for me was that SGN answered a column-and-gradient question in writing without asking why I wanted to know.
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.
