Collecting this in one place because it comes up every few weeks and the answer is always assembled from scratch. It is about cross-border ordering, and it is deliberately narrow — everything I am not confident about is marked as such.
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.
Cold chain is the underrated risk on long routes. A shipment held at a border for a week has had a temperature excursion whether or not it arrives.
What would genuinely help is knowing which of the variables in a cross-border order actually determine the outcome, and which are superstition. I would rather have one careful answer than five confident ones.

Right, and one flattering data point from a group buy is not consistency. Consistency means separate batches, separately commissioned, over months.

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.

Browse GL BiochemShort answer first, then the reasoning. Prices dramatically below market are the strongest single signal, and the reason is arithmetic rather than suspicion. Synthesis, testing, and cold-chain shipping have floors. A price well under the floor means something was skipped, and the two things that get skipped are testing and content.

Adding a me-too, because a thread of one person's experience is not much use.
