tarheel, I have not been to the Psily Shop, but will try to locate it on my next reach at the end of July.
I have been to Cone, Cup & Stick located near the front gate to Catcha Falling Star and directly across the street from Seastar Lane.
My first experience was with the Patoo chocolate bar. It has three sections. 4g bar.
I took one of the three pieces on three separate days and had a decent experience. It did require me to lay down for about an hour or so.

On a different trip, a buddy of mine bought the dried Patoo Mushrooms from a different venue. He consumed the entire bag in the course of several hours and didn't get much out of it.

My recollection is both products were about $90 US. I was pleased with my experience, but my buddy was not.

Enjoy,

VVHT
