[Vendor] HJ — small operation, honest about lead times, that is worth something
Title is the summary — HJ — small operation, honest about lead times, that is worth something — and the detail is below in the order it happened.
Started buying small deliberately, tested every lot for the first four, then stopped testing every lot because there was nothing to find.
Kept a spreadsheet of quoted versus actual lead time across 6 orders. The quoted number held.
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.
Please do not ask me what dose you should be on. I genuinely do not know and neither does anyone else here.

nofollow and sponsored; nobody here is paid for it.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.
Correction: that supplier is in the documented twenty with a source page, not in the wider-market table. Different evidence bases entirely.
the source page log is more useful than the score above it
Fixing my own comment above: I said 5 orders and it is 21. The pattern is the same, the count was wrong.
Right — FGP publishes the method line on the certificate, and once you have seen one that does you notice every one that does not.
Amino Asylum came up in three threads the week I was ordering and I could not find a single independent result for them anywhere. Went with a documented supplier instead.
Tracking number redacted from the post above. It identifies both ends of a shipment.
Small fix — the figure you quoted is the claimed purity from the certificate, and the independent result was the higher of the two.
Did you ask for the batch-specific certificate, or the generic one?
Mild pushback: a supplier with fewer entries is not worse, it is less sampled. Those are different claims and the table says so.
a claim with no batch number is a marketing document
lead time quoted at checkout is the number to hold them to
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.
a supplier that answers method questions in writing has already told you a lot
Regional stock made more difference to my planning than anything else — ordering from a warehouse in the Netherlands took the customs question off the table entirely.
A certificate with a purity figure and no method line is not falsifiable. You cannot reproduce it, you cannot check it, and it tells you nothing about how the number was produced.

Agreed — and the corollary is that "no data" and "bad data" have to be written differently. The table separates them for exactly that reason.
Lead time and minimum quantity are the two facts people forget to ask for and then argue about later. Both are answerable in one email before you commit.
the wider-market names in the table are there because nobody has enough data on them

Would qualify this slightly. Fewer entries means less sampling, and less sampling is not the same as a worse process.

This is the whole method in one sentence. Everything else in the thread is elaboration.
Where a supplier holds regional stock, ask which lines are actually held there rather than drop-shipped. It changes the lead time and it changes the customs question.
Minimum order and lead time — did they quote both up front?
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.
