bouncing bear sucks for san pedro. i wouldnt use them for anything.
How does one obtain this stuff? I hear it's pretty hard to find in synthesised form
you extract it from cactus with one of the many methods on this site or find a vendor in china that sells it in synthetic form and ships to your country. don't ask me the name of any vendors i wont share.
mescaline is the rarest thing to be looking for on the black market. most people who extract it themselves dont sell it because there is little profit to be made and not much yield from most teks. you will almost always have to make it yourself.
99% of the time when someone sells you a capsule of powder calling it "mescaline" its a research chemical.
