Import rules for personal quantities, by jurisdiction, dated

On the subject in the title: Import rules for personal quantities, by jurisdiction, dated Working notes rather than a conclusion.

Structured report rather than an opinion, following the format the maintainers asked for.

• Compound: semaglutide
• Independent testing: VendorInvestigate
• Method as reported: reversed-phase HPLC, 220 nm
• Result: 95.9% area
• Certificate figure for the same lot: 99.2%

I am not drawing a conclusion about the supplier from one lot and I would ask that nobody else does either. I am adding a data point to a record.

Practical note that does not fit anywhere else. Whatever you conclude from this topic, write down what you did and when. The single most useful thing in your own records is not any individual result; it is that they are dated and consecutive.

post #2 answers the question as asked. The question underneath it is different.

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.

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.
