This follows the opening post rather than contradicting it.

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.

Worth separating two things that the opening post 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.

Picking up post #3: that is the part I would want checked first.

For anyone arriving from a search: the marked solution above is the direct answer, and the replies underneath it add the caveats that make it safe to use.

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.

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.
