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 98.2% purity
International ordering adds complexity but can save 60-80% compared to US prices. Research your country's import laws first.

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.

Worth separating that from vendor vetting, which this thread keeps folding into the same question. They behave differently and the advice does not transfer.
