Kratom

I'm from VA, I've been in Puerto Rico for 5 days and have run out of kratom. I was scared to bring as much as I needed because I wasn't sure if TSA would throw it away and it's expensive. anywhere near San juan, the rain forest, or luquillo that sells it. any leads would be appreciated. I get sick if I don't have it and really want to be able to enjoy my trip. it's stunning here.
