If i order amps of vials from an overseas source how likey is it that they will not make it to me due to customs? Should i just stick with stealth garbage or should i roll the dice on amps?

It's a true dice game, soldier.
If you order a huge amount.....1K amps or so and they get inspected, you WILL be on notice for a controlled delivery.
Stay small and don't get too greedy and you'll be straight, bro.
