Living somewhere the domestic route does not exist, which makes most of the advice on this board inapplicable to me.
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.
If the honest answer is that nobody knows, that is a useful answer and I would rather have it.
Taking the question as asked, rather than the general version of it. 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.

Agreed, with a caveat about community reputation: it is a lagging indicator. Reports arrive weeks after orders, so a supplier can look excellent for a month after quality has already changed.

Right, and one flattering data point from a group buy is not consistency. Consistency means separate batches, separately commissioned, over months.
Clinical perspective, offered as context rather than as advice.
My experience ordering cross-border ordering internationally: I've ordered from a Canadian pharmacy. Customs can be hit or miss.
Shipping time: 10-21 days
Customs clearance: held for 3 days then released
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.
