Stay hydrated as you tend to forget to eat/drink when you've dropped acid. Start by taking one tab. It's very much influenced by what you make of it. You can either think yourself into fucked up situations and get overwhelmed and start imagining things or you can enjoy the sweet 3000 fps and inner peace.
Acid is fun I've done 100-150 ug a few times, 300ug a couple times and 500ug once. Just gotta make sure you can handle it, and make sure ur actually consuming lsd-25
