Painfree only uses privnote, not pgp, but $48 for a gram of morphine powder that I could convert right into pure heroin with the help of a simple 'make your own aspirin' kit sounds too good to be true. Any experience? He has tons of listings for the same product which is a second red flag to me, but his feedback seems pretty good both on the forum and market.
home bake is pretty easy to make, but acetic anhydride is a list 1 chemical, I don't know how easy it is to get in the US without drawing scrutiny. I know there is someone that sells it on ebay, and I know its really easy to get overseas. You can use glacial acetic acid though to get a combination of 3-MAM and 6-MAM (kind of like black tar heroin without the tar issue). I'd suggest against it though, just buy a half gram of heroin or just shoot morphine. Its too much trouble unless you are going to convert a bunch of it.
