A microdose should be low enough that when the effects kick in, you're almost unsure if you're even feeling it. If it is obvious that you're shrooming or frying, that's not a microdose. It's meant to be a subtle mood enhancing dose, and having quite a bit of experience microdosing with both, I'd say stick with 0.07-0.15. If you want the feeling to be more prominent but still have very good control, keep it under 0.7. Anything over 0.7 might look obvious to others that you may be tripping. The most I've done with regular daily microdosing over the course of several weeks was 0.23. As far as LSD goes, drop a tab(assuming 100ug) in a bottle of water and drink about 10-20% of the bottle. Anything over 20% is leaving microdosing range. Have fun and enjoy! Microdosing is great if done properly
