Living somewhere the domestic route does not exist, which makes most of the advice on this board inapplicable to me.
The narrow version of the question is 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.
This one has a reasonably settled answer, so here it is. 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.

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

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.
Adding the clinical framing, because it changes how the question reads.
International shipping tracking for cross-border ordering orders: my experience with customs in the US when ordering from overseas:
Seized and destroyed — had to get a reshipped package.
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.
