help me understand reship, I have read the wiki twice

Needs Source Clean Column ×1 Sourced ×3

help me understand reship, I have read the wiki twice — that is what I am asking, and I have already read the wiki twice.

Hangzhou Meite Bio 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.

Kept a spreadsheet of quoted versus actual lead time across 10 orders. The quoted number held.

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.

If two or three other people have done the same thing we might actually learn something. Alone it is an anecdote.

Flair set to Vendor. Also a reminder that we take no money from any supplier in the directory.

Flair set to Vendor.

paper_trail_paula is describing the batch record test and it is the fastest signal available before you spend anything.

consistency across lots beats one spectacular result

Fixing my own comment above: I said 15 orders and it is 34. The pattern is the same, the count was wrong.

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.

lead time quoted at checkout is the number to hold them to

reship policy in writing before the order, not after

registration number, then everything else

Correction: that supplier is in the documented twenty with a source page, not in the wider-market table. Different evidence bases entirely.

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.

Inter-lab variance on this assay runs a point or two either way. Two services disagreeing by that much is agreement, not a discrepancy, and treating it otherwise starts pointless arguments.

what does the certificate actually carry — that is the whole question

Did the lot code on the vial match the paperwork?

u/camila_sandvik-9 points·10 months ago

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.

The thing that decided it for me was that BCH answered a column-and-gradient question in writing without asking why I wanted to know.
