Cold-chain shipping — which vendors use proper temperature control?

Prices dramatically below market are the strongest single signal, and the reason is arithmetic rather than suspicion.

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.

Agreed, with a caveat about community reputation: it is a lagging indicator.

Thank you for spelling out the reasoning rather than just the conclusion. I will report back once I have actually tried it.

I disagree that testing history is decisive. It tells you what a supplier did when they were being watched. Continuity of behaviour under stress — a late shipment, a failed test, a complaint — is more predictive than any run of good results.

Adding the numbers, since they settle part of this. Worth stating the units and the reference range whenever you post a number here. A large fraction of the apparent disagreement in these threads is two people using different units and both being right.
