Oh lolzolzOLZOLZololz, Im sure a PO box would be fine, I think some states make you like give a bunch of identification to them or something like that. What state do you live in? You dont have any friends houses to ship it to?
Didn't you just have a pretty negative experience with research chemicals? Why the hell would you wanna order more?...

I got a P.O. Box for this very reason. i'm younger than you and there wasnt really anything suspicious about it. You need two forms of identification. I had to use my Vehicle Insurance card and my drivers license. they needed like some weird shit for proof of address besides your drivers license and i didnt have anything else they wanted besides the vehicle insurance card on me so I'd recommend having that cause i can't remember the other things that they needed to see. If they asked for why i wanted a P.O. box my excuse was gonna be some ramble about online identity theft prevention. they never asked though.
