I've tired out Woodrose seeds (LSA) and shrooms. Neither were particularly tasty, although. Woodrose seeds additionally are a bit dangerous as their active range is pretty close to their "I'm gonna do organ damage" range -- but both of them were easy to legally buy on the internet

I'm still a bit hesitant to go try out 1D-LSD (since you can currently still legally buy that) I'd love to get my hands on pure LSD but state suppression and stuff
