And then get to sell the stamps you made yourself and nobody knows if you fly or cry, when taking it? You better already have a trusted distributor, already in the game, waiting. Probably you should not distribute it anywhere to close to home. You'll want to have any issues related to it, to exist preferably in another universe.

There are many more things to consider and plan beforehand, unless the plan is not to sell drugs.

I think I remember reading there's a legit tek somewhere out there; the catch is that there are also a lot of fake teks, either because they're supposed to be satire, or because someone's trying to look good on a random forum and they know no one will actually try it due to equipment requirements. Additionally, I think you can technically do it with stuff at home, but the quality and yield would probably be shit, which is something you don't want to fuck with when it comes to ergot.
