Vendor shipping speed comparison — need advice

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

My experience ordering cross-border ordering internationally: I've ordered from a Canadian pharmacy. Customs can be hit or miss.

Shipping time: 10-21 days
Customs clearance: held for 3 days then released
Quality: Janoshik tested at 99.1% purity

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

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.

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

One concrete data point for the thread. Give anything pharmacological four weeks before you judge it, and give anything measured weekly a four-point rolling average before you call it a trend.
