they are frustrating cus each batch has different levels of the various active ingredients (LSA bein the main one), so one time you might just get sick, and feel lethargic, then another time its damn close to trippin on acid, then another time it might be like a combination of the two aforementioned experiences. I had to go through 4 lame trips (different batches each time), before i had a good one, but it turned out to be worth it, cus the trip was great.
