Def. lsd in the shiva's It ain't swiss crystal thats for sure but their lsd-25 probaly a lower grade crystal is all beats the twins at 80-90 ug at the price 15 to trip come on now!Its not that i do not believe the shivas are acid, but i think it must have some dirty xtal on this batch or something because the things feel totally unclean. Backache , stomach in knots, intensely confusing headfuck, and a rough jittery comedown. Nothing like the stuff i was getting prior to these.
