depends on the poitincy of the hit my first trip I took 1 and a half and that was one of the most awsome trips I have ever had
Not a lot. Most shit that is "acid" isn't acid. Doses vary widely from dealer/maker to dealer/maker and since you're talking micrograms thats a good bit of difference. Take it, if you start to trip balls just relax and enjoy it and just go with it. If you don't trip you will probably get a body high which is still pretty great.
my first time i apparently had really good cid, what my friends said, and i took 1 tab and was tripping balls, palm trees were smiling at me, everything "breathed", and closing my eyes id see fractals spinning i also took 3 rolls tho too, not sure how much that enhanced the visuals, but i do know i was having a full body orgasm for 10 hours and could barley move
Assuming that you don't get ripped off, anywhere from a very mild weed-like high to walls melting. Only one way to find out...
