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 97.6% 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.
