Research-use-only labelling: what it means and what it does not

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.

Worth separating two things that post #9 runs together.

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.

This follows post #26 rather than contradicting it.

I disagree with the reply above, and I think the disagreement is substantive rather than terminological.

The distinction being drawn does not survive when you look at the published data for this specific question. I would be glad to be shown wrong on this, because the version I am arguing against is more convenient.

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

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

Preclinical versus clinical: compounds with strong preclinical data can fail in clinical trials. Compounds with no human data are being used on theoretical grounds. The regulatory position reflects this asymmetry.

Thank you for the correction. I have edited my earlier post with a note rather than silently, so the thread still makes sense to read. The error was mine and it was the kind that comes from remembering a figure instead of looking it up.

Why this category is maintained as documentation, not as recommendations: the goal is factual accuracy and sourcing, not endorsement of any specific regulatory position.
