I tried SL-164 from Longflourish. Very nasty side effect, involuntary muscle twitching. Never saw this from the real deal back in the 70s and 80s (I'm old as dirt). Otherwise was just a clumsy, sloppy disorientation then sleep.
I used them on the Dweb, they sent me garbage. Supposed to be 3-meo-pcp, they sent me some gummy greyish-yellow crap that was wet with solvent and smelled like poison. Left out overnight to dry a bit but it was still gummy and very much off-color. I was afraid to consume and it went right...
