Tried 500ug a few times and that's already a fucking heavy mind-shattering trip. It's not exactly fun. Also lasts forever, with stuff like 2C-E the peak is over after 4 hours and you feel somewhat clear headed again, but high doses of LSD completely wreck you for at least 8-10 hours.
Trips should be positive and fun - 150ug is more than enough already, especially when you mix it with cannabis.
This.
