Bro there's really no risk with domestic orders. Think about it. Like one day a thought hit me, I was like, for all they know, all those kratom bags may as well be big bags full of illicit powder or some illegal chemical. Never had an issue and I'm sure never will.
I get Pregabalin is scheduled in the USA but still you're totally good. To the U5PS employees it may as well be a bag of kratom or makeup or literally anything. I promise it's not a real issue to worry about
