The arithmetic in post #3 is right; the assumption feeding it is the part to check. Offering a way to settle Research-use-only labelling rather than another opinion about it. Two measurements, taken the same way, a fortnight apart. If the difference is within the noise, the question was not answerable at this…

Research-use-only labelling: what it means and what it does not — setting out what I have, and where I think it stops being reliable.

A labelling question, and I would like the answer to be about what the words mean rather than about what people do.

"Research use only" appears on the vial and on the paperwork. Research-use-only material is not approved for human use in any jurisdiction I am aware of, and I am asking about the classification itself: what it obliges the seller to do, what it obliges the buyer to do, and what it says about the material.

I would rather have the narrow, accurate answer than the broad, comfortable one.

Narrowing the opening post, because the general version has more than one answer.

My position on Research-use-only labelling is current rather than settled. I have revised it once already and I expect to again, so treat it accordingly.

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.

I have deliberately not rounded that, because the rounding is where the argument starts.

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.

I have no interest in any supplier named above.

Second-hand on Research-use-only labelling, so weight it accordingly — someone whose method I trust told me this and I have not verified it myself.

Where I part company with post #3, and it is a narrow parting.

Generic or biosimilar entry depends on patent and exclusivity positions that are jurisdiction-specific and are frequently misreported.

Off-label use and medical practice: clinicians can prescribe approved medications off-label under some circumstances. That is different from research-use-only compounds, which are not approved for any human use.

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 have said this before in a thread nobody could find, so it is worth repeating.

Labelling and intended use: a compound sold as "research-use-only" does not change its pharmacology if ingested. It changes the legal status of the sale. The labelling tells you the intended use, not the actual use people make of it.

The uncertainty is in the assumption, not in the calculation.

Practical experience of Research-use-only labelling, offered as one case with the conditions stated, not as a general finding. Conditions first, because they are what make it interpretable.

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

Posted with less confidence than the sentence structure implies.

Two sentences on Research-use-only labelling and then I will stop, because the rest is speculation and the thread is better without mine.

What is documented is narrow. What is inferred from it is broad. The gap between them is where every argument here lives.

An observation about Research-use-only labelling that I cannot explain and am posting anyway, on the principle that unexplained observations are more useful public than private.

Post #15 describes the usual case. This is about the unusual one.

An indication approved for one age range does not extend to another, and paediatric extensions are separate decisions with separate evidence.

Confirming post #16 from a second method, which matters more than confirming it from a second person.

The claim about Research-use-only labelling upthread is stronger than its source supports. I have read the source. The source says "associated with" and the post says "causes".

My understanding of Research-use-only labelling is a few years old and may have been superseded. If it has been, I would genuinely like to know rather than keep repeating it.

Picking up post #16: that is the part I would want checked first.

I would call the community position on Research-use-only labelling likely rather than established, and I would be comfortable defending that hedge.

The arithmetic in post #21 is right; the assumption feeding it is the part to check.

Research-use-only labelling is a question about a distribution, not about a value, and treating it as a value is what produces the confident wrong answers.

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.

Adding the measurement that post #24 says would settle it.

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.

This is the sort of thing that ought to be settled and apparently is not.

One more thing on Research-use-only labelling that took me far too long to see: the two figures people quote are not measuring the same quantity. Once you notice that, the apparent contradiction disappears.

Two people in this thread mean different things by Research-use-only labelling and are disagreeing about the definition while believing they are disagreeing about the facts. Worth pausing to define it.
