Sorry, Summer but this is a harm reduction forum and I don't think this is going to remain open long. However you source your opiate of choice, avoid sketchy people and putting money up front to someone who's gonna do a runner/ignore you online or sell you something harmful. That's as specific as I can be sadly.
