Revisiting: Why a compound being unapproved is not the same as being illegal to possess posts 61–83

This is a continuation of a long topic, addressed by post number rather than by page. Start at post 1.

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 checked the source rather than the summary, and they differ.

c.okafor, post #23: Post #20 answers the question as asked. The question underneath it is different. A regulator's public assessment report is usually the single best free source on a compound's evidence base, and it is almost never cited here. Stating my assumptions rather than smuggling them in. Go to post

Helpful, and short, which on this subject is harder than long.

Narrowing post #60, because the general version has more than one answer.

The claim about compound being unapproved upthread is stronger than its source supports. I have read the source. The source says "associated with" and the post says "causes".

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

Where I would look next, rather than where I would stop.

Compound being unapproved has a well-known answer and a correct answer, and the interesting work is establishing that they are the same. Nobody has done that here yet.

k.farrugia, post #31: I think the compound being unapproved question is answerable and has not been answered, which is a more optimistic position than most of this thread. Go to post

Post #63 and I disagree about the size of the effect, not about the direction.

A compound in a compounding pathway in one country and unavailable in another is a common situation and produces most of the confusion here.

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.

Scoping that to what I have actually seen rather than what I have read.

The documentation on compound being unapproved is better than this thread and I say that as someone who has posted in the thread.

Confirming post #68 from a second method, which matters more than confirming it from a second person.

Filing a mild objection to the consensus on compound being unapproved. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit.

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.

Import restrictions vary by compound and by jurisdiction: what is a controlled substance in one place is legal to purchase in another. What you can import for personal use depends on your country's rules, not on where it is sold.

I have no interest in any supplier named above.

Confirming post #69 from a second method, which matters more than confirming it from a second person.

A regulator's public assessment report is usually the single best free source on a compound's evidence base, and it is almost never cited here.

The general answer and the answer for your case may diverge here.

k.batista, post #41: Compound being unapproved: I would want to see the raw numbers rather than the summary before agreeing. Summaries lose exactly the information that would settle this. Go to post

Adding a reference point for compound being unapproved. Mine is a single case, collected without controls, and I am posting the method alongside it so it can be discounted appropriately.

Compound being unapproved is a question about a distribution, not about a value, and treating it as a value is what produces the confident wrong answers.

Coming back to post #73, because the follow-up matters more than the original answer.

Approval versus licensing: a compound can be approved for a specific indication in one country and not approved at all in another. Tracking jurisdictional approval is tedious but necessary.

I would treat the number as indicative rather than as a measurement.

Post #73 is right about the mechanism and I think understates the practical bit.

One more thing on compound being unapproved 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.

Tavares, post #52: Genuine question rather than a rhetorical one: has anyone here actually observed compound being unapproved, as opposed to read about it? The thread is long and I cannot tell. Go to post

Summarising the compound being unapproved thread so far, since it is long and the answer is buried: the first reply has the method, the fourth has the correction to it, and the rest is people agreeing at length.

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

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

Marking my uncertainty on compound being unapproved explicitly. I am confident about the direction, much less confident about the size, and not confident at all that it generalises past the case in the first post.

Agreed on compound being unapproved, with one qualification that I think matters. The reasoning holds for the case as described. Change the starting assumption and it does not, and the starting assumption is the part nobody states.

Adding the measurement that post #78 says would settle it.

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

Worth one more sentence than it usually gets.

Regulatory positions change: a compound's status today might differ from its status a year from now. Citing a regulatory position is worth doing only with a date attached.

The interesting part of this is the exception, and I do not understand the exception.

Trying to state the compound being unapproved position in a way that someone who disagrees would recognise as fair, because I do not think the version in this thread passes that test.
