it's hard to get safrass oil... you can order it from china though... i'm not sure which sites though etc.

sign up on either bluelight or totse.com

go on the forums and ask their...

bluelight is a forum centered around ectasy, and totse is about chemistry etc.

And yes it's difficult, but you don't have to be a scientist... it can be done, but i don't advise doing it. There are good pills out there, it's just hard to find them.
