My experience ordering cross-border ordering internationally: I've ordered from an Australian compounder. Customs can be hit or miss.
Shipping time: 5-10 days
Customs clearance: was seized once, reshipped free
Quality: Janoshik tested at 99.5% purity
International ordering adds complexity but can save 60-80% compared to US prices. Research your country's import laws first.

Saving this. It is the first explanation that did not require me to already understand it. Adding it to my notes with a link back to this thread.

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.
