I quckly checked and reason.com say 80% of American raw drug material is produced abroad, in 150 countries. Countries like Ireland, India, China, Israel etc.
BUT where are the illicit drugs produced? It's not like they fall out the back door in Switzerland. China produces everything, though sometimes only the precursor chems so a cartel orders them and their chemists do the last steps. China is king of all counterfeits, what other country could compete?
I don't order online but there's some UG steroid firm in the UK called Ghost-something. My buddy said everything is available, in whatever packing or labeling you want, like call it "bhanks test 500," "only via prescription, protect from sunlight."

UK fellas here can correct me if I understood wrong.
