Getting consistent results from microdosing depends heavily on how you store your materials and prepare your doses. Even the best protocol and the most self-aware tracking are undermined if your dose varies unpredictably because of degradation or inconsistent measurement.
Storing Psilocybin Mushrooms
Psilocybin degrades when exposed to heat, light, moisture, and oxygen. Proper storage is about minimizing all four.
Drying. Mushrooms should be thoroughly dried before long-term storage. Truly dry mushrooms snap rather than bend. A food dehydrator set to around 95°F (35°C) works well. Air drying is possible but slower and less reliable, particularly in humid environments.
Containers. Store dried mushrooms in airtight containers—mason jars with good seals work well. Include a small silica gel packet to absorb any residual moisture. Store in a cool, dark place. A cupboard works; a freezer works better for long-term storage.
Whole vs. ground. Whole dried mushrooms store longer because they have less surface area exposed to air. Ground mushroom powder degrades faster. If you plan to grind your supply (recommended for consistency), do so in batches rather than all at once, keeping the rest whole.
Timeline. Properly stored dried mushrooms retain potency for months at room temperature and a year or more frozen. Poorly stored mushrooms can lose significant potency within weeks.
Preparing Consistent Doses
Consistency is the cornerstone of useful microdosing. If your dose varies significantly from day to day, you can't accurately assess what's working.
Grind and mix. Take your dried mushrooms and grind them to a fine, uniform powder using a coffee grinder or dedicated spice grinder. Mix the powder thoroughly. This averaging process reduces the natural potency variation between individual mushrooms. For more on potency variability and how to assess what you're working with, see our article on sourcing and quality.
Capsules. Filling capsules with measured amounts of powder is the most common preparation method. Size 00 or 0 capsules work well. A milligram scale accurate to 0.01 grams is essential—kitchen scales aren't precise enough. Capsule filling machines are available for larger batches.
Weigh every dose. Even with a capsule filling machine, weight can vary slightly. Weigh each capsule to verify consistency. This adds a few minutes to preparation but significantly improves reliability and reduces the chance of accidentally taking too much.
Storing and Preparing LSD
LSD is remarkably potent—active at microgram levels—and correspondingly sensitive to degradation.
Storage essentials. LSD degrades with exposure to light, heat, and moisture. Wrap blotter paper in aluminum foil, place in an opaque container, and store in the freezer. Handle with clean tweezers—finger oils can degrade the compound.
Volumetric dosing. The most accurate way to microdose LSD is volumetric dosing. Place a tab of known (or estimated) potency in a measured amount of distilled water or high-proof alcohol. Let it sit for 24 hours in the dark. Then use an oral syringe to measure precise volumes—each milliliter contains a known fraction of the total dose.
For example, if a 100-microgram tab is placed in 10 milliliters of distilled water, each milliliter contains approximately 10 micrograms—a common microdose starting point.
Amber glass bottles protect the solution from light. Store in the refrigerator (not freezer, as the solution shouldn't freeze).
Working with Truffles
Psilocybin truffles (available legally in the Netherlands and elsewhere) require different handling than dried mushrooms.
Fresh vs. dried. Truffles are typically sold fresh and are about 50-70% water. Dried truffles are roughly 3 times more potent by weight. A fresh truffle microdose might be 0.5–1.5 grams, while a dried equivalent would be roughly 0.15–0.5 grams.
Storage. Fresh truffles should be refrigerated and used within a few weeks. For longer storage, dry them using the same process as mushrooms—low heat, good airflow, until they snap cleanly.
General Best Practices
Label everything. Note the substance, date of acquisition, preparation date, and any potency information you have. Memory is unreliable, especially over weeks and months.
Maintain hygiene. Treat preparation with the same cleanliness you'd apply to food preparation. Clean tools, clean surfaces, dry hands.
Keep records. Track which batch you're using and any observations about potency. If batch 3 seems consistently stronger than batch 2, that's useful information for dose adjustment.
Prepare in advance. Many people find it helpful to prepare a week or month's worth of doses at once, in a calm, focused setting. This avoids the temptation to eyeball a dose when you're rushed in the morning.
