To be honest I would prefer not to discus Darius in this thread. We have this practice to ship labels separately. But all vials are marked in this case and in one package are vials of only one type. say 1 package with test p only. and nothing more inside. labels shipped separately We do this for our resellers if they ask for this. As a rule we do this only for really big resellers which order big amounts, where custom is really a problem. I am speaking generally, independent on the country. This helps. Of coarse in this case responsibility for correctly labeled vials is on our resellers. We can not control this remotely. In any case possibility to mix up something and stick a wrong label is low. As you noticed our caps have different colors for different compounds, it helps a bit as well.
As for our USA basicstero store, we shipped vials and labales separately to our first reseller, I never hided this and mentioned that some labels can be sticked crockedly, there were even photos here. Our reseller scammed us and disappeared. We started working with our bulk customer / employee, the first restocking he received from us was also like this - vials and labels separately. Cause we already had parcels ready to ship to the old reseller and he scammed us. With our new employee we found another way to transport gear and we don`t restick labels now. You always get vials with labels stuck an the factory. However we still have vials in USA stock with resticked labels. They all are correct I am sure. By the way within about 2 weeks we expect a big restocking of hour USA warehouse. All vials will be not touched. All orals in blisters.
Replying your question, there are not always ways and opportunities to import into some country gear in genuine packages and with genuine labels. This all is illegal in the most countries of the world, don`t forget it.
Also i think the less we talk about it the better. I probably revealed already too much info. The less we talk about it the more it is safe for both you and us.
