A microdose is usually 0.1 to 0.3 g of dried mushroom, and the whole range is only 0.2 g wide. Knowing the number is easy; weighing it is the hard part. Here's the scale you actually need, how to grind and mix so every dose matches, and when pre-filled capsules are the simpler choice.
A microdose is usually 0.1 to 0.3 g of dried mushroom, which is 100 to 300 mg. On our dosage chart, a 160 lb (73 kg) adult with some experience lands at 0.17–0.26 g of Golden Teacher. Your own number depends on your body weight, your experience and the strain, and the dosage calculator works it out for you, so we won't repeat the maths here.
Outside sources give much the same range. Harvard Health describes a microdose as typically around 0.3 g and names varying mushroom potency as one of the obstacles to studying it. Whatever range you land on, start lower than any chart says.
The gap between the bottom and the top of the microdose range is 0.2 g. Every measuring problem below comes down to errors about that size, which is why precision matters far more here than with a full dose.
A kitchen scale can't measure a microdose. Most read in 1 g steps, and the finer ones read in 0.1 g steps. One 0.1 g step is the size of a whole low microdose, so the display can show the same number for 100 mg and 190 mg.
Resolution isn't the whole story. Resolution is the smallest step a scale displays; accuracy is how close that display is to the true weight. Cheap scales often list an accuracy of plus or minus a couple of their smallest steps, so check the spec, not just the number of decimal places.
| Scale type | Reads in steps of | Good enough for a microdose? |
|---|---|---|
| Kitchen scale | 1 g | No. It can't tell 0 g from 0.4 g. |
| Fine kitchen scale | 0.1 g | No. One step is a whole microdose. |
| Pocket or jewelry scale | 0.01 g | Workable at 0.15 g and up, borderline at 0.1 g |
| Milligram scale | 0.001 g | Yes. This is the one to buy. |
The same weight can give you a different dose because psilocybin isn't spread evenly through a mushroom, or evenly across a batch. A 2026 study of 14 Psilocybe cubensis strains, all grown and dried under the same lab conditions, measured psilocybin from 2.03 to 19.60 mg per gram (PMC). Individual mushrooms within the same strain still varied by roughly 13% to 23%.
So if you snap 0.15 g off one mushroom on Monday and 0.15 g off another on Thursday, you've taken the same weight but not necessarily the same dose. Caps and stems can differ too. Some studies find more in the caps, others find similar levels, and either way you can't tell by looking.
The fix is to grind the whole pack into one powder and mix it well. A lab study of several cubensis strains found measurements were more precise when multiple mushrooms were blended together before testing (ScienceDirect). Grinding doesn't make anything stronger. It averages out the strong and weak pieces, so each 0.15 g scoop sits closer to the pack's average.
Measuring a microdose at home takes a 0.001 g scale, a grinder and a clean, dry jar. Here's the process in order.
Put a 0.001 g scale on a flat, hard surface, let it warm up, and check it with the test weight.
Grind all of it at once, a full 5 g for example, to a fine, even powder in a clean spice or coffee grinder. Lumps and fibres mean uneven doses.
Tip the powder into a dry jar, close it and shake it well. This step is what makes dose 1 match dose 30.
Put a folded piece of paper or a small weighing boat on the scale and zero it.
Add powder a little at a time with a small scoop until you reach your number, 0.15 g for example. Tap off the extra rather than pouring.
Note the date, the weight, the strain and how the day went. A notebook is how you tell whether 0.15 g is right or 0.1 g would do.
Close the jar tightly and put it somewhere dark and dry, as covered in the storage section below.
SSRIs and other antidepressants can blunt effects, and MAOIs and lithium can be dangerous in combination, so talk to a healthcare professional first if you take prescription medication. A personal or family history of schizophrenia, psychosis or bipolar disorder is a genuine reason not to use psilocybin. Don't use it while pregnant or breastfeeding. If you're struggling, the SAMHSA National Helpline is free, confidential and open 24/7 at 1-800-662-4357, or call or text 988.
Filling your own capsules is cheaper per dose, but every capsule has to be weighed one by one. A capsule holds well over a microdose (ours go up to 600 mg), so filling one to the top won't give you 150 mg. The only way to know what's inside is to put each one on the milligram scale.
Here's the cost comparison at our prices. A 5 g pack is $100. At 150 mg a dose, that's about 33 microdoses, or roughly $3 each, plus a scale, a grinder and empty capsules. Pre-filled 150 mg capsules work out to $10 each in a pack of 10 and $6.50 each in a pack of 80.
| Option | Price | Doses at 150 mg | Cost per dose |
|---|---|---|---|
| Dried, 5 g | $100 | About 33 | About $3, plus equipment |
| 150 mg capsules, 10 | $100 | 10 | $10 |
| 150 mg capsules, 40 | $280 | 40 | $7 |
| 150 mg capsules, 80 | $520 | 80 | $6.50 |
If you don't mind the process and own a good scale, dried is the better value, and our 5 g packs come in all three strains. If you'd rather not spend an evening weighing powder, that's what capsules are for.
"Filled to 150 mg" means each capsule holds 150 mg of dried, ground mushroom material, not 150 mg of psilocybin. The same goes for our 350 mg and 600 mg strengths. It's the same unit as the gram figures on the dosage chart, so a 150 mg capsule lines up directly with a 0.15 g dose.
You can check a capsule yourself. On a milligram scale it'll read a little above 150 mg, because the empty shell adds its own weight. For what's actually in the mushroom, every batch is lab-tested and we keep a Certificate of Analysis (COA) for each one. A COA is the lab's report on what it found in that batch; text us at (971) 370-8474 and ask for yours.
Capsules don't change the fact that mushrooms vary in strength. What they remove is the weighing. If you want a fixed weight with nothing to grind, our pre-filled 150 mg capsules start at $100 for 10, and every order comes with free dosage guidance and a real person to answer questions about strain, strength or timing.
The same 0.15 g is a stronger dose in Albino Penis Envy or Albino Bluey Vuitton than in Golden Teacher. Our chart assumes Golden Teacher potency. With APE or ABV, start at the bottom of your range or below it.
| Strain | Potency by weight | Measuring note |
|---|---|---|
| Golden Teacher | Balanced, forgiving; the chart's baseline | Use your calculator range as given |
| Albino Penis Envy | Among the most potent cubensis strains | Start at the bottom of the range or below |
| Albino Bluey Vuitton | High but manageable, stronger than GT | For people who already know their dose |
If you switch strains, drop back to a lower dose and take notes on how each dose feels, even if you'd settled on a number. A milligram scale makes that easy: a step down from 0.15 g to 0.1 g is just a different reading.
Keep ground mushroom in an airtight jar somewhere dark, dry and at room temperature. In a study of how psilocybin breaks down during storage, dried mushroom kept in the dark at room temperature lost the least, and fresh mushrooms stored frozen lost the most (Oregon Health Authority copy of the study).
Our dried mushrooms and capsules arrive vacuum-sealed. Leave a pack sealed until you're ready to grind it.
