Pharmaceutical compounding rules, summarised from primary sources — a second dataset

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.

Primary documents matter: regulatory positions are published in official documents. Reading the regulatory agency's website directly is more reliable than reading a forum summary of it.

Worth separating two things that post #13 runs together.

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.

Compounding and pharmacy rules: some jurisdictions allow a pharmacy to compound a drug that is not on the market under specific conditions. The conditions are strict and vary by jurisdiction. Generalising from one country's rules to another's is unreliable.

Coming back to post #17, because the follow-up matters more than the original answer.

Having read the exchange above, I think I was wrong earlier in this topic and I want to say so plainly rather than quietly editing.

The correction was fair and I had been repeating something I had not checked carefully enough.

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.

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

Two things before anyone answers the substance.

First, the context in the first post is clear and specific. Second, the question is framed so that an answer can actually address it. Both are the norm here and both matter more than they sound.

post #22 answers the question as asked. The question underneath it is different.

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.

On post #20 — agreed on the reasoning, with one qualification.

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.

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.

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.

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.

Worth separating two things that post #24 runs together.

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.

Picking up post #26: that is the part I would want checked first.

Compounding and pharmacy rules: some jurisdictions allow a pharmacy to compound a drug that is not on the market under specific conditions. The conditions are strict and vary by jurisdiction. Generalising from one country's rules to another's is unreliable.

Coming back to post #28, because the follow-up matters more than the original answer.

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.
