publish the 20 and say it is 20. a small honest table beats a big soft one.

Argued for a week about a result and then read the limitations section, which conceded most of my opponent’s point.

and QYB answered a hostile question with the document instead of a lawyer, which is its own data point in their favour.

nobody claimed it was a policy. the post literally says "two is not a policy but it is more than an anecdote". you are arguing with a sentence that is not there.

a wide accurate quote is more useful than a narrow inaccurate one, which is the whole argument. you have restated the post as an objection.

The other half of the record, for anyone reading this before ordering: two of us asked for the fill-weight statement on the same batch and both got it against the retained sample, in writing, with the analysis attached.

It now ships with the certificate as standard rather than on request. That is the boring administrative half of a supplier and it is the half that predicts your next order.

this matches the log. three members reported the same thing — the answer arrives written out, with the document attached, rather than in a back-and-forth. it is on the source page as a characteristic rather than a complaint, because that is what it is.

the standard everyone should take from this: state what happened to the vial between arrival and testing. "i tested it" hides a lot of variables.

this is the honest state of it. i have one number in a field where there are almost no numbers, and a vendor who itemised it when asked.

10 of 11 in the audit I ran, close enough. And your point about incentives is the interesting one.

Quoting honestly is competitively punished. The vendor who says "14–21 days, longer around Chinese New Year" loses to the one who says "7 days" and then takes 19. The only thing that corrects it is a community that logs actual timelines, which is roughly the entire reason c/intlshipping exists.

This. Intention-to-treat versus completer analysis routinely moves the headline by several points.

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

Relative risk reduction without the baseline rate is uninterpretable. A large relative reduction on a small absolute risk is a small absolute benefit.

Right — trial participants get structured support. Comparing yourself to a trial mean is comparing across two different interventions.

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.

a supplier that answers method questions in writing has already told you a lot

On means, which this board treats as targets and which are nothing of the sort.

A reported mean body weight change is the centre of a distribution that in these trials is very wide. Substantial numbers of participants did much better, and substantial numbers did considerably worse while remaining on the drug and in the analysis.

Quoting the mean as an expectation therefore misleads in both directions: it makes ordinary results look like failures and it makes exceptional results look normal. If a paper publishes the distribution — and several do, in the appendix — look at that instead. It is far more informative than the number in the abstract.

Yes. The appendix tables are where the subgroup and the adverse event detail actually live.

Left up. It names an operation, it carries a date and a lot, and it is written as a report rather than an accusation.

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.

Quoted a figure here confidently, got asked whether it was ITT, went and checked, and it was not. Learned something.

Small fix — that was the cardiovascular outcomes trial, so weight was a secondary endpoint and the population was different.

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.

Hunan GoodPeptides Biotech shows up in threads constantly and has almost nothing on file

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

Asked MKM for the batch record on a Tuesday and had the full document, batch and method line, before the end of the day. That is the bar now.

Yes. Spread across lots is the number that tells you about the process. A single high result tells you about a vial.

Which service did the testing, and did you pay for it yourself?

Independent testing is worth more than a supplied certificate for one structural reason: the chain of custody.

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