If it's truly pure LSD, 100ug is plenty. Many hits sold as 100ug really aren't.

That being said, you are more likely to be fine than not on 125ug-175ug, but responses are really variable. I've discovered that I'm very steady on psychedelics and so I can handle physical discomfort (jitteriness etc) and not have a bad time, but there's a certain archetype of individual that has trouble handling the raw barrage of stimulus that tripping represents.

So, you would probably be okay but I would recommend no more than 100ug taken in a natural setting (rather than being stuck inside your house).

Cheers.
