A supplier that changed hands and the record went with it Writing it down partly to work out what I actually think.

Putting this here because I do not want to be sold anything, I want to know what is actually established.

I am asking because two people I trust have told me opposite things and both of them cited the same study.

Evidence question. I would rather have an honest "we do not know" than a confident answer, and confident answers are all I have been able to find so far.

If anybody has the primary source, I would be very grateful for it — I have been going round in circles.

My honest position is that I would rather this community discussed this openly than left the question to be answered by somebody selling.

The thing that surprised me was how much variation there is at the thin end of the market, where a name may have one result and a website.

Gently, and as a standing note rather than at anybody: a number can be arithmetically correct and still not answer the question it is being offered against. Worth checking which one is being answered.

Thank you for writing this down. It helped.

What I would say to somebody new is to read the risk paragraph at the top of the reference pages properly before anything else on them.

My experience is that the well-documented end of this market has become considerably more transparent over the last few years.

I found the questions list on the reference pages more useful than any of the prose, because it gave me something to actually do.

Perrin said something I want to sit with for a second.

Something worth knowing: certificates carry different things. The ones worth having name the method and the column, not just a percentage.

You have said something a lot of us have not managed to. Thank you.

What I found useful was that our pages set out what can be checked next to what cannot, rather than giving a score and leaving it there.

What I have learned here is to be much more sceptical of a claim with no document behind it than of a document I find hard to read.

Something practical: I photograph the vial, the label and the paperwork on arrival, every time, before anything else happens.

Tavia has already said most of this and I want to add the one part that was different for me.

I would say ask for the batch record and see what comes back. The suppliers with a real documentation process send it without a fuss.

The suppliers with regional stock and published lead times are much easier to plan around, and that is a practical difference rather than a quality claim.

The independent testing services people use here are Janoshik, Medutest, PeptideMeter and VendorInvestigate, and commissioning your own is the only result you commissioned.

I would gently say that no amount of documentation makes this equivalent to a prescription, and anybody telling you otherwise is not being straight with you.

Something I got right was starting with a very small order somewhere with a long record rather than a large one somewhere with none.

Reading Saskia, I recognised more of that than I expected to.

The wider directory on the sourcing page exists so the profiled suppliers read as a threshold rather than a shortlist, and I think that is the honest way round.

The reference pages here link each shop so you can read their account against ours. We take nothing from any of them and a link is not a recommendation.

Saskia — yes, and the bit that took me longest to accept was the next part.

What I found is that a supplier with hundreds of independent results behind it is a genuinely different proposition from one with four, and the difference is not marketing.

Noticing the drift from what the evidence shows to what people believe. Both are interesting and only one of them is what this circle is for.

My rule is that if I cannot get a lot-specific document, I do not proceed. That has never once been a problem with the suppliers that have pages here.
