I know it's better to be more paranoid than not. But a little goes a long way.
packages get seized... sometimes it's just on rotation for certain locations rather than red flag on a specific location or rather than a suspicious eye setting its gaze upon you.
One seized package even with indictation isn't really so much a heavy cause of concern. Of course, some other factors may weigh in.
Like ordering stealth or simply not ordering when it's likely to arrive during an election time, there's been a terror alert or media craze for certain ports - keeping up on custom news is a good thing to have in the long run. Definitely to be considered when in you're in North Amerika or the UK.
Creating a paper trail. Often people around here seem to want to hide their footprints. If worse comes to worse, it's better to have some breadcrumbs marking the way you want them to go. For the paranoid inclined, Keeping a separate sheet of "records" is important for your overseas supplementals, even if you're intended to make credit purchases or going through another online service, consider getting an international money order for a random amount and either donate to a cause worthy of an investigation, purchase from a non-gear else overseas and mark it in your logs as your primary or cash it back out to yourself in a couple days, keep the receipt and log it as an expense towards fictionalized company for protein shakes and other supplements. Unless you're part of a sting, they aren't going to search far. So having a trail is beneficial in the long run and all they have is circumstantial.
So, Another typical is if you're receiving gear (every few months or multiple packages per year) regularly from overseas locations then also order some non-gear from various overseas or gear that you know is legal as alternative in addition to your orders. While it's not per se an adequate defense, it does cast a shroud of doubt... and it was just a fluke that steroids were found in one.
If you want to whig them out then you make an inquiry on it... the majority of people have something seized rarely make an inquiry about it. Which in a way is an admission of guilt.
Worse comes to worse.
If you got a letter then it's sort of a common for a person to want to ensure this isn't going to effect their possible future, so it looks less suspicious to make an inquiry and sum it up as a bad purchase for something that was advertised via spam or classifieds, as a safe, *legal, effective alternative. A couple squigs for a miracle drug or spending on average 600 or more at the health food or over-priced GNC shop. Even if it sounds too good to be true, what would they do?
Of course, if you can't keep a game face, don't do it. And if it's happened more than once, don't do it.
Another option, although a bit more difficult for the average bloke, get a prescription, even though technically it's supposed to be under medical supervision often insurance won't cover the costs associated with the use of a steriod or HRT, so more people are inclined to try to handle it on their own and there's enough of public legal aide dedicated to the cause medical affordability and consumers stepping outside of the bounds in the states with a little more head room to move around in. But again, it's not really an adequate defense... just something else to put on the table.
but eh, whatever.
