My experience ordering cross-border ordering internationally: I've ordered from a UK pharmacy. Customs can be hit or miss.
Shipping time: 7-14 days
Customs clearance: smooth, no issues
Quality: Janoshik tested at 98.3% purity
International ordering adds complexity but can save 60-80% compared to US prices. Research your country's import laws first.

Thank you — that is the clearest version of this I have read, and I have read a lot of them. Printing the relevant bit and taking it with me.

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.
