Volumetric Dosing and the Art of Getting Your Microdose Right

For well over a year, I just cut up little tabs. I'd take a standard blotter tab and try to split it into ninths. Tiny, uneven pieces. Some looked bigger than others. I'd eyeball it, pick one, and hope for the best.

Some days I'd barely notice anything. Other days I'd be sitting at my desk wondering why colors looked a little too bright. That's not microdosing. That's gambling with your attention span.

The thing nobody tells you when you first start microdosing is that the method matters as much as the dose. Maybe more. You can follow the Fadiman protocol perfectly, track your off days, journal like a saint, and still get inconsistent results if you're guessing at how much you're actually taking each time. That's where volumetric dosing comes in, and it changed everything for me.

What microdosing actually is (and what it isn't)

A microdose is a tenth to a twentieth of what you'd take for a full experience. Small enough that you shouldn't feel high. Small enough that you could go to work, have a conversation, live your day. The whole point is that the effects are sub-perceptual: if you can tell you took something, you took too much.

The two most common substances people microdose with are LSD and psilocybin mushrooms. Not everything works for this. MDMA, for example, isn't a good candidate because it can't be used consistently without risk, and it doesn't produce the kind of subtle, cumulative benefits that make microdosing worthwhile. Cannabis produces too noticeable an effect at any dose to really qualify.

And here's what catches a lot of people off guard: a single microdose isn't the point. You won't feel a dramatic shift from one dose. Microdosing works on a protocol, taken over several weeks, with rest days built in. It's a practice, not a pill.

The protocols: Fadiman, Stamets, and finding your rhythm

A protocol is just a schedule of when you dose and when you rest. The most well-known is the Fadiman protocol, created by James Fadiman, who is probably the single most important researcher in the microdosing space right now. His recent book with Jordan Gruber, Microdosing for Health, Healing, and Enhanced Performance, is the most thorough resource out there if you want to go deep on the research.

The Fadiman protocol works like this: dose on Day 1, take Day 2 as a transition day (you may still feel subtle lingering effects, sometimes called the "afterglow" or second-day effect), then Day 3 is a full rest day back at baseline. Repeat. You run this cycle for four to eight weeks, then take at least half that time off, so two to four weeks of rest before starting again.

The Stamets Stack is another popular option, developed by mycologist Paul Stamets. There's also an every-other-day protocol that some people prefer. Each has its own rhythm, and our full breakdown of Fadiman vs. Stamets vs. custom protocols goes into when each one makes sense.

Why I stopped cutting tabs (and you should too)

Here's what I learned the hard way: blotter paper isn't always evenly distributed. The LSD is laid onto the paper, but it doesn't soak in uniformly across the entire surface. So when you cut a tab into nine pieces, you're not getting nine equal doses. You're getting nine mystery doses.

On top of that, handling blotter constantly with your fingers isn't great for potency. And try cutting a tab that's maybe 7mm square into nine even pieces with scissors. It's not happening. I'd end up with little confetti shapes, some clearly bigger than others, and I'd pick the one that "looked right." Precise, it was not.

This is the biggest practical gap in how most people start microdosing. They read about the Fadiman protocol, they get the schedule down, and then they take wildly inconsistent doses because the method of preparing their dose is just... eyeballing it.

Volumetric dosing: the method that actually works

Volumetric dosing solves the precision problem. The concept is simple: instead of trying to physically divide a tiny piece of paper, you dissolve it in a measured amount of liquid and then measure out your dose by volume.

Here's how it works with LSD. Take one tab and drop it into 100 mL of distilled water (or high-proof alcohol like vodka). Let it sit for about 24 hours, shaking it a few times to help it distribute. A standard tab is roughly 100 micrograms (mcg) of LSD. Once it's dissolved, 1 mL of your solution equals approximately 1 mcg. Want a 10 mcg microdose? Measure out 10 mL. Want 15 mcg? Measure 15 mL. That's it.

The liquid distributes the substance evenly in a way that cutting paper never can. You go from hoping you got the right amount to knowing within a reasonable margin.

Storage matters more than you think

Once you have your solution, you need to protect it. UV light degrades LSD. Store your solution in an amber glass bottle, or wrap a clear bottle in aluminum foil. Keep it in the fridge (not the freezer, since frozen liquid isn't very useful). I keep a larger "source bottle" in the fridge and a smaller amber dosing vial with milliliter markings for daily use.

I experimented with pre-filling individual vials for each dose day, thinking I could just grab one each morning. It sounded efficient but ended up being more hassle than it was worth. Pouring from the source bottle into the dosing vial each time you need it is faster and simpler. Sometimes the obvious approach is the right one.

The solution itself doesn't taste like much of anything when you use distilled water. It's a small amount of liquid, so most people just take it straight like a tiny shot. You could add it to a drink, but there's really no need.

Psilocybin microdosing: the capsule method

For psilocybin mushrooms, the approach is different but the principle is the same: get consistent doses. The standard method is to grind your dried mushrooms into a fine powder (a coffee grinder works well) and pack the powder into capsules using a small scale to weigh each one.

The exact weight will vary by strain, but the target is that same one-tenth to one-twentieth range of a standard dose. Capsules have the added benefit of being easier on the stomach than eating raw mushroom material. Some people also prepare their psilocybin as a tea or use a lemon tek method for digestion comfort.

Capsule filling kits are available at sites like microdosing.nl and other European vendors. These kits come with a grinder, a scale, and a capsule filling tray, so you can prepare a full batch at once. You can also find similar setups on Amazon.

What legalization looks like in practice

If you want a glimpse of where microdosing is headed, look at what's already available in parts of Europe and Canada. Sites like microdosing.nl and Chemical Collective sell legal research chemical analogs (like 1P-LSD and 1cP-LSD) in forms designed specifically for microdosing.

They offer pre-made pellets where each one is already dosed correctly for a microdose. No math, no dissolving, no guessing. They also sell tinctures that work like a pre-made version of volumetric dosing: a few drops from a calibrated bottle. It's essentially what we're doing at home with distilled water and blotter, but packaged with precision manufacturing behind it.

It's worth checking these sites out even if you can't order from them, because they show what a regulated microdosing market could look like. Pre-dosed, tested, labeled. That's the future. For now, we're the ones who have to create that precision ourselves, and that's exactly what volumetric dosing does.

Practical tips from someone who got it wrong first

Less is more. People who microdose over longer periods tend to settle on lower doses. When you're starting out, go with the smallest amount you think might work and adjust from there. You can always increase. Coming down from an accidental full dose at your desk is a bad time.

Set and setting still matter. Even at sub-perceptual doses, your environment affects your experience. The same dose will feel different at home on a quiet morning versus at work during a stressful meeting. Anxiety, worry, and bad moods get amplified, even at small amounts. This is true for full journey preparation and it's true for microdosing too.

Watch your combinations. Caffeine can amplify anxiety. Alcohol effects get stronger. Nicotine hits different. If you're going to microdose, be aware of what else is in your system. A lot of people report that microdosing made them more sensitive to their daily substances, not less.

Always test your substances. I keep saying it because it matters that much. You can get reagent test kits from DanceSafe and Bunk Police, and potency testing from Miraculix. These are partners we trust and recommend. Knowing what you have and how strong it is makes everything that follows safer and more predictable.

Frequently Asked Questions

Can I just cut up blotter paper for microdosing?

You can, and a lot of people start this way. But LSD isn't distributed evenly across blotter paper, and cutting tiny pieces accurately is nearly impossible. Volumetric dosing gives you much more consistent results with very little extra effort.

How long does the volumetric solution last?

Stored properly in an amber bottle in the fridge, a solution can last several weeks to months. The key is protecting it from light and heat. Distilled water solutions may not last as long as alcohol-based ones, but both are fine for a typical microdosing cycle.

What's the difference between the Fadiman protocol and the Stamets Stack?

The Fadiman protocol follows a dose-day, transition-day, rest-day cycle. The Stamets Stack involves microdosing four days on, three days off, typically combining psilocybin with lion's mane and niacin. We break down both in detail in our microdosing protocols comparison.

Do I need to test my substances before microdosing?

Yes. Every time, full stop. Reagent test kits from DanceSafe or Bunk Police confirm you have what you think you have. Potency testing from Miraculix tells you how strong it is. Both matter for safe, accurate dosing. Visit our resources page for direct links.

Can I microdose with MDMA or cannabis?

These aren't recommended. MDMA can't be used on a consistent schedule safely due to its effects on serotonin, and cannabis produces noticeable effects even at small amounts. The most well-studied and commonly used substances for microdosing are LSD and psilocybin.

Where can I learn more about preparing for a microdosing practice?

Our free downloads page has a microdosing tracker you can use to log your protocol. For a complete system including dosing guidance, journaling frameworks, and integration practices, the Microdosing Protocol is included in our Complete Journey System.
