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.
The bit I cannot resolve on my own is which of the variables in a cross-border order actually determine the outcome, and which are superstition. Tell me what I have not thought of.

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

This is where I part company with the consensus forming above. 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 BiochemTaking the question as asked, rather than the general version of it. The useful checklist is about verifiability rather than presentation. Independent test results commissioned by buyers rather than by the seller, consistency across multiple batches over time rather than one flattering report, a physical address and a company registration that resolve, batch and lot numbers on the actual labelling, and a shipping practice that matches what the material needs. Everything a good-looking website provides is cheap to fake; none of the items above are.

Same pattern here, and in the same order. I had assumed I was the exception until I read this.
