I'll just write up a few tips as someone who has ordered lotsa drugs from the DN.
- ship [your country]>[your country]. There is always a risk your package could be intercepted but not going across borders greatly reduces the chance of this. Also if you are ordering a relatively small amount of drugs (i.e. personal use only) and it does get confiscated, you will prob only get a letter saying it's been seized with no legal consequences or nothing at all.
- pay extra for tracked shipping. it's not usually loads extra but it will give you more peace of mind that it's coming.
- sometimes vendors scam and don't send it/sell impure products. check market reviews and/or check Dread (basically reddit but .onion) to find a good vendor that sells what you want.
- buy test kits and test your drugs. always. just because you're suicidal doesn't mean you need to be stupid about this.
- ANONYMISE EVERYTHING. when you set it all up you'll have to set up a keychain which encrypts and decrypts messages on these vendor sites. you'll want to anonymise your name, address, etc. the way these work is like a one way key that only you and whoever you are messaging have, and without it you cannot read the information written. it looks like code. this way, if a market ever gets breached, your info won't be on there and it can't be traced back to you. also use a whole new username, email address etc. you're fine using a real name and address IF YOU ENCRYPT IT.
hope that kinda helps - i don't wanna be too specific since it could be against the rules but yeah! stay safe
