Fentanyl isn't the de facto thing anymore, it's even prohibited to be sold on any darknets.
What's not illegal and and plentiflully available heard them more stronger, lethal and narcan immune analogs Metoetazine, Isometoetazine, ..... And so forth. The analogs are not considered illegal analogs because they are completely different animal so structurally different that they're a headache to classify. I died by one of those analogs a few years ago. It was easy to order on the DN and dirt cheap too with no legal risk or liability that your question makes me wonder ...
What is preventing people from getting these 5,000x times stronger than fent analogs?
You don't even need a VPN, Tor or any of that stuff.... It's all built into the the Tails or Kodachi OS
Just get a Flash drive, download Kodachi iso file, and Flash it to a thumb drive or flash drive using Etcher or Rufus.
That's it! Kodachi has a built-in VPN, PGP encryption decryption tools and billions of other security apps. Just launch Tor and get a valid Dark Net Market link from Dark.Fail, Tor.taxi for the famous underground forum Dread.
Create an account Bohemia is my favorite, and then buy.
What's this whole scare about the legality of it? There's millions of users and people are afraid that the DEA is going to spend 10 million dollars into an investigation into some random person that suicidal to track them down and indict them?
I've been ordering stuff from the dark net for decades now, and none nothing that I've ordered has ever been seized by law enforcement. But if you're afraid, that's what they'll do they'll just seize the package and you'll get what's called a "love letter" in the mail.
If you really want to die peacefully and painlessly in a bliss of euphoric explosion you're going to have to jump through if you hoops.
Nobody's going to spoon feed you a quick and easy death, although there's dozens hundreds of tutorials and a lot of people willing to help out with technical stuff.
What would prevent one from jumping through those hoops? Hmm
