One order arrived in nine days, one was held at the border for a fortnight, and one came back with a seizure notice.

International shipping tracking for cross-border ordering orders: my experience with customs in the US when ordering from overseas:

Required FDA import alert review, delayed 10 days.

Tips: always include a copy of your prescription, declare medication properly on customs forms, keep quantities reasonable (personal use = 3 month supply max), and use a vendor who has experience shipping to your country.

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 97.5% purity

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

This is my experience too, for whatever a second data point is worth. The detail I would add is minor and it is already implied above.

Clinical perspective, offered as context rather than as advice. The honest answer is that the effect is real, the magnitude is contested, and the individual variation is larger than either. Those three things can all be true at once, and most arguments here are two people holding different parts of that.
