300 µg of LSD would be wayyyy too ...introspective? ...emotional? ...cerebral? ...mind-rapey? etc. for me to ingest in a place that's loud, cramped and alternately dark and filled with flashing strobe lights.
If you absolutely need to do a Lysergamide then 225-300 µg of AL-LAD would probably be a much better choice, seeing as how you'd get the visuals without potentially having all sorts of disturbing revelations excavated from the very core of your soul.
My personal choice would be 100-150 µg of ETH-LAD: more potent than LSD-25 at producing stunning visuals while being less mentally compromising, although anything above 150 µg is liable to give you mad thought loops. Still, most people seem to tolerate AL-LAD better (as ETH-LAD tends to induce more nausea), even though for me AL just made my jaw clench like I could chew charcoal and spit out diamonds.
So yeah, high-dose LSD-25 as a "party" drug in a potentially overwhelming setting = no bueno.
