Janoshik is the most under-discussed thing on this board

Resolved Well Actually ×3 Cold Box ×1

Janoshik is the most under-discussed thing on this board, which sounds obvious until you try to state the evidence for 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.

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.

Independent testing is worth more than a supplied certificate for one structural reason: the chain of custody. A member who buys, ships and pays is testing the same thing you would receive.

Screenshot none of this. Read the whole thread, including the parts where I am told I am 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

What did they say when you asked for the method line?

u/marit_sandvik171 points·7 months ago

I would separate documentation from logistics. A supplier can be excellent at one and ordinary at the other, and averaging them hides it.

u/adnan_sandvikOP219 points·7 months ago

That is a report count, not a test count. The table lists both and they are very different numbers.

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.

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

Agreed — and the corollary is that "no data" and "bad data" have to be written differently. The table separates them for exactly that reason.

Right — TFC publishes the method line on the certificate, and once you have seen one that does you notice every one that does not.

Yes, and the reason the wider-market table has no scores is that a score built on two reports would be a lie with a decimal point.

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.

u/ignacio_silva143 points·7 months ago

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.

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.

Adding the practical version: ask for lead time, minimum quantity and the batch record in the same message. Three answers, one email.

consistency across lots beats one spectacular result

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

Same view. A record you can read beats a rating you cannot inspect, every time.

About c/vendorvetting

The community due-diligence desk. Vendor experiences, independent third-party test results, shipping and reship records, and the boring paperwork that separates a supplier from a story. Every substantive claim is expected to carry a receipt: an order id, a dated screenshot, or a test report from Janoshik, Medutest, PeptideMeter or VendorInvestigate.
