500ug isn't that much. 75ug is a threshold dose IIRC, with most street doses coming in around 150ug.

Taking 4 blotters is not that out of the ordinary is it? In the 90s in London, when LSD was cheap as dirt, I knew a lot of folks who would dose like that.

Are you joking? You must be seriously experienced to handle 500ug. If you gave that dose to a beginner, they'd be scarred for life.

Or perhaps just young, stupid and completely carefree..

(edit - I certainly wouldn't like to do that now)
