It depends on how you’re doing it, (and how it was stored, because the molecule is pretty fragile and breaks down easily) but typically a single hit would be in the ballpark of 90-110 micrograms. So 500x would be about 0.05 grams. Which is a truly astronomical amount of LSD. Probably not the highest ever recorded, (that honor goes to a couple of idiots who thought it was cocaine and snorted it), but still a mind-meltingly high amount.
That highest dosage (while technically unknown, because we only have the ER reports when they showed up completely comatose) is estimated that they had somewhere between 1000 to 2100 hits each. And they survived. So at least Toad isn’t in danger of OD’ing.
