Haha... I literally searched for this for years to include in the bible. I even traveled to South Africa on the back of a tip that I could buy it from a pharmacy. I couldn't. Apart from this the quaaludes on sale on a market a few years ago turned out the be the extremely dangerous fake, SL-164.
So, good luck with this, but if you do find it, I'll be jealous, BUT do make sure you send it for testing. Stay safe. :-)
hahahaa, I feel I'm talking with a long lost twin, i did exactly the same, minus the traveling. Closest i found was a reddit group of weirdos who fetishize with finding old medication tablets and vials and shit, and there's quite a few photos of ludes from who-the-fuck-knows when. I read somewhere that in south africa they still synthesize it in clandestine laboratories and sell it, is it not the case anymore?
