I would just go pick it up.Shit. My packs have always been left at the door. There was no attempted delivery in this case. If I didn't check tracking, I wouldn't have known... I'm chalking this up as "seized." Oh well.
They do not have the time, money, or resources to have an DEA or FBI team staked out at your local post office just in case you might show up one day (they do not know if or when you may show up so they would need the team there everyday waiting) for a small order of steroids and/or ancillary meds.
This is not like you have been trafficking kilos of coke.
If your pack was searched and seized, it would have occurred at US customs (right after the ICS step on tracking), NOT at the local post office -- contraband is not allowed to continue past ICS and Customs and enter the country.
Don;t waste the good supplements or your money; Go get your stuff
