I think I mentioned this in another thread, but I have confirmed with 2 trials that AL LAD does not cause LSD tolerance, which came as a huge surprise. In both trials, which used different batches of LSD, 150 mcg of AL LAD was eaten the first evening, followed by 200 mcg LSD the following night, with no diminished effects. Pretty much full-on 200 mic acid trips. However, I have not tried it the other way around. From my 2 experiences, my sense is that there is something missing from the effects of AL LAD (as compared to LSD) that prevent it from down-regulating receptors the way LSD does. AL LAD definitely lacks some of LSD's magic (at least at equivalent doses), but it is still a fun and pleasant LSD-type buzz that has this awesome tolerance loophole, the only one I have ever heard of!
