So, you can see from the above advice that people have varied opinions/experiences related to customs seizures.
My experiences have been that a couple of years ago I had a pack from an int'l source seized by customs on the West Coast; I received my 'seizure' letter & tossed it. At the time, I was advised not to use the same address to receive any AAS.
Currently, at a different address (and different source), I had a couple of seizures on the East Coast. In both instances, I did not receive a 'seizure' letter...I was able to track the pack from the overseas source to FLA using the tracking number. However, in that instance, the pack just seemed to disappear in FLA. I never received a seizure letter or any other notification. My source resent to the same address & I received it w/o incident. In a more recent case, the pack was confiscated by the overseas customs officials (according to the source, they have worked out some sort of arrangement with the U.S.). The pack has since been resent and made it through the overseas customs & is currently on its way here.
So what this all means is: just because you had something seized doesn't mean (1) you will get a seizure letter & (2) you can't use that address to receive any other AAS.
So, take this information, along with the other previous experiences, and access your situation. If you do get a seizure letter, you can just toss it. Personally, I don't believe you have anything to worry about as long as the quantity of AAS you order indicates personal use rather than distribution.
