What is the every other day microdosing protocol?

It is the simplest microdosing rhythm: a dose day, then one off day, repeating. Dose, off, dose, off. It is easy to remember, but the single off day leaves a tighter margin against tolerance than schedules with two or more rest days.

Is every other day microdosing too often?

It is tighter than the most common schedules. The Fadiman protocol uses two off days and the Stamets Stack three, specifically to manage tolerance and give more baseline. A single off day works for some people but leaves less room before the effect starts to fade, and fewer ordinary days to compare against.

Which is better, every other day or the Fadiman protocol?

For beginners, Fadiman is usually the safer starting point because its extra off day gives a cleaner baseline and more tolerance margin. Every other day suits people who have learned their response and prefer a simpler, more frequent rhythm.

The Every Other Day Microdosing Protocol, Explained

The every-other-day protocol is the most stripped-back microdosing schedule there is: dose one day, rest the next, repeat. It is appealingly simple, and it comes with one real trade-off worth understanding before you choose it. This guide covers both. It is educational only and gives no amounts.

The schedule in one line

Every other day is exactly what it sounds like:

Day 1: a dose day.
Day 2: an off day.
Day 3: a dose day again.

And so on, alternating. There is nothing to remember beyond "every other day," which is part of its appeal.

How it compares to the other schedules

The main difference between schedules is how many off days sit between doses, and that one number drives everything:

Fadiman protocol: one on, two off.
Stamets Stack: four on, three off.
Every other day: one on, one off.

Every other day has the tightest spacing of the three. That is the whole story of its strengths and weaknesses.

The trade-off: tolerance and baseline

A single off day means two things, and both cut the same way.

First, less margin against tolerance. The classic psychedelics build tolerance quickly, and one rest day leaves a tighter buffer than two or three. Some people are fine with it; others find the effect starts to flatten faster than on a more spaced schedule.

Second, fewer baseline days. The off days are your ordinary days, the ones you compare dose days against. With only one off day between doses, you have fewer clean reference points, which can make the pattern slightly harder to read, especially early on. The off day still matters as an integration day; there are just fewer of them.

Who it suits

Every other day tends to work best for people who have already run a more spaced schedule, learned their own response, and decided they prefer a simpler, more frequent rhythm. It is less ideal as a first protocol, precisely because the tighter spacing makes the early weeks a little harder to interpret, and the early weeks are when clarity matters most.

If you are completely new, the more common advice is to start with Fadiman's wider spacing, learn your baseline, and only move to a tighter rhythm like this one if it appeals later.

Making it work

Whichever way you go, the fundamentals are the same: keep the amount genuinely small, do not chase a fading effect by tightening further or dosing up, watch for tolerance, and above all track it. With a tighter schedule, consistent records matter even more, because the contrast between dose and off days is subtler when they sit right next to each other.

That is what Dose Days handles: it lays out whichever rhythm you choose, separates dose days from off days, and surfaces the pattern across the cycle so a tighter schedule is still readable. Free to start, private by default.

A note on safety

Microdosing involves controlled substances and an early research base. None of this is medical advice or a recommendation to use anything. Understand the law where you live and speak to a qualified professional about your situation. There is a fuller safety and legal note in the Fadiman protocol guide.
