There are a few microdosing protocols out there. Even folks new to the game might be aware of some of these — the Stamets Stack is a fairly well-known option for consumers, as is the Fadiman Protocol, invented by the godfather of microdosing himself, Dr. James Fadiman.
Some people like to keep things simple and take a dose every other day. I used to commit to the Stamets stack, but I’ve found that the “every other day” rule seems to work best for me.
I’ve also spoken to people who microdose on a different scale, with a once-weekly dose of around 400mg to ride the micro-high all the way to the next.
