There's always a chance that your shit will get picked up. It's less likely given these circumstances, but still a possibility. Just send over a vial of test e or c to a couple different places just so you've got enough to cruise while you're gone. If it gets snagged up, who gives a fuck.. just a single vial.
How long as you leaving for? I'm just presuming that it's no longer than a few weeks, maybe a month.
