Disclaimer that I ALWAYS test my shit with the Ehrlich reagent and have never gotten anything that didn't screen for LSD.

Back in my old city I was getting stuff from a friend of a friend and although it was pretty decent I would always get issues with body load- feeling restless or even nauseous wasn't an uncommon side effect. I always struggled with insomnia on that stuff too.

The last 2 years I've been buying from online sources and the first batch I got I had minimal (but not none) body load and less insomnia. However, I did get more auditory hallucinations on that stuff (nothing scary typically) and saw more halos, tracers, etc than I had before. I think I can chalk this up to how they were dosed.

The newest batch I got comes highly recommended and accurately dosed at 155ug per tab. I've taken it twice now, and it's the best acid I think I've ever tried. Absolutely phenomenal head space, and ZERO body load apart from the occasional shiver. One tab had me sailing through the evening on a puffy cloud. Visuals were good but nothing crazy, I've definitely had much more intense visuals on similar doses.

My question is what causes these variations between different sources? I know acid can't be cut with anything, so why do some sources cause more body load and other side effects and some don't? The stuff I just got is LSD-25, I'm wondering if previous sources could be 1P-LSD and this could account for the variation? If anyone has any insight, TIA.
