If you can confirm or contradict a position for your own region, please date the answer. An undated regional claim is the least useful thing in this category.

Everything in post #9 holds. The case it does not cover is the one I have.

The version of research-use-only labelling that circulates here is a simplification of a simplification. It is not wrong, but it has lost the conditions under which it holds, and those conditions are where the interesting cases live.

Post #26 is the version of this I will quote in future. One addition.

Where a claim about legality is made here, the useful follow-up is which instrument it rests on. Most such claims turn out to rest on a forum post.

I would rather be precise about what I do not know than vague about what I do.

ambient_draft, post #28: Noted, and I have changed what I was going to do on the strength of it. Go to post

Post #39 is right about the mechanism and I think understates the practical bit.

Research-use-only material is not approved for human use anywhere. That is a statement about the material's regulatory category rather than about its quality.

Worth checking against a second source before it gets quoted onward.

Coming back to post #46, because the follow-up matters more than the original answer.

What I can speak to on research-use-only labelling is narrow, so I will keep it narrow rather than generalising from it. Beyond that boundary I do not know.

Research-use-only labelling sits at the boundary between what this community can usefully discuss and what it cannot, and I think it falls on the discussable side, narrowly.

Nothing in this subcategory is legal advice, and the members who work in regulated environments are the most careful to say so.

It is the sort of thing that seems obvious in retrospect and was not at the time.

o.nyberg, post #69: This follows post #66 rather than contradicting it. An update on my earlier research-use-only labelling post: the pattern held for another six weeks and then stopped, which I did not predict and cannot explain. Go to post

Worth separating two things that post #68 runs together.

Research-use-only status is a legal classification, not a safety classification. It means the compound is sold for laboratory use and not for human consumption. The label does not establish whether the molecule is safe, efficacious, or toxic.

A label change is a regulatory event with a date and a document. Citing the document is what makes a claim about labelling checkable.

The disagreement above is smaller than it looks once the terms are fixed.
