After the Bohemia debacle, Arcetype is the only reliable market ATM. Surprisingly the only one with the most liberal fent/opioid RC rules. I've just ordered 1g of china white (fent) and 2g Metoetazine for $200 from a veteran vendor (shite, 2,000,000 mg , probably enough to euthanize my entire town or die by opening the package from dust vapors for those with no tolerance).
To make things easier I'd recommend the all in one VPN-Tor-DNS-GPG-Wallet gold standard OS on a disk Kodachi OS.
Just google Kodachi and flash it on a tumb drive with Rufus, boot up F12 and select Live OS on RAM. Basically the whole operating system exists on RAM (can run on a barebone PC without a hard drive) and when you're done just hit the nuke shutdown button and it'll wipe itself without a trace. Built in VPN with failsafe trigger, and a gazillion GUI user friendly interface features. Just have a separate tumb drive to store your sensitive data (KeePass password vault, wallet backups, etc...) on an encrypted seperate flash drive. Plug in the first Kodachi and boot from it, then plug in your other data flash drive.
