This gets cited here weekly, usually second-hand, so it is worth setting out what it does and does not establish.

The variables that decide how a cross-border order goes are declaration wording, the destination country's import rules for prescription medicines, and whether the shipment looks commercial. Personal-import allowances exist in some jurisdictions and not in others, and where they exist they are usually conditional on a prescription and a quantity limit. The failure mode is normally a seizure notice rather than anything worse, and a reshipment policy is the thing worth confirming before ordering rather than after.

Where I think it is weakest: the completion rate deserves as much attention as the headline, because a large effect among those who finished is a different claim from a large effect among those enrolled.

So the question, as narrowly as I can put it: which of the variables in a cross-border order actually determine the outcome, and which are superstition. If the honest answer is that nobody knows, that is a useful answer and I would rather have it.

Note on sourcing:
Figures above are from the primary publication rather than the press summary. If a number here disagrees with one you have, post yours and we will work out which of us is reading a secondary source.

My experience ordering cross-border ordering internationally: I've ordered from an Australian compounder. Customs can be hit or miss.

Shipping time: 5-10 days
Customs clearance: was seized once, reshipped free
Quality: Janoshik tested at 99.1% purity

International ordering adds complexity but can save 60-80% compared to US prices. Research your country's import laws first.

Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. Import rules are jurisdiction-specific and this board keeps giving US-shaped answers to non-US questions. What is a personal-import allowance in one country is a controlled-import offence in another.

International shipping tracking for cross-border ordering orders: my experience with customs in the US when ordering from overseas:

Held at customs for 5 days, then released.

Tips: always include a copy of your prescription, declare medication properly on customs forms, keep quantities reasonable (personal use = 3 month supply max), and use a vendor who has experience shipping to your country.
