If you need it soon, it's a bad idea.
If you're scared of customs seizing your pack, it's a bad idea.
If you don't want to end up on a blacklist when the FDA opens your pack and notices steroids.
Now if you aren't on a blacklist, your address hasn't been flagged, if you are a first time buyer and have never ordered international then I highly recommend ordering a shit ton of raws and rolling the dice to see what happens. Make that one time big time order and if it doesn't make it then at least you knew you gave it your all.
If you're a buyer with a clean record as far as customs is concerned then I envy you, I remember those days, I remember marveling at the large sacks of beautiful powder melting away in oils, dreaming of gallons of brew, but sadly those days are over for those of us on the US customs shit list.
