Why the lab figure matters

Most mushroom potency talk is anecdotal. An independent test figure lets you actually calibrate: at 1.8% the same weight delivers substantially more than an average strain. Whatever you would normally take, take meaningfully less here, and confirm it against the scales rather than by eye.

Not a starting point

This exists for people who already know how they respond to a full experience and want more depth from it. If that is not you yet, the balanced strains are where to begin.

What you get

Dried and cured to snap rather than bend, which is how you know the moisture is under control. Sold by weight, sealed and shipped discreetly.

Weigh, do not estimate

Mushroom caps and stems vary enormously in density, so eyeballing a dose is genuinely unreliable. A cheap set of scales that reads to 0.01g removes the biggest source of error in the whole process, and costs less than a single order.

Finding your dose

The common reference points for dried material are roughly 1g for a light experience, 1.5 to 2.5g for a moderate one, and 3.5g or above for a strong one. Those are averages rather than rules, and potency varies between strains and between flushes. Start a step below where you think you belong and work up across separate sessions.

Onset and timing

Allow a full 45 to 90 minutes before you consider taking more. Topping up because the first dose seems slow is the single most common way people end up further out than they intended. The experience typically runs four to six hours from onset, with a long gentle tail after that.

Set and setting

Where you are and what frame of mind you are in shape the experience more than the exact figure on the scales does. Somewhere familiar and comfortable, a clear day with nothing you need to be sharp for, and ideally someone sober around the first few times. Plan the landing as well as the take off.

Who should avoid this

Anyone with a personal or family history of psychosis or bipolar disorder, anyone pregnant or breastfeeding, and anyone taking SSRIs, MAOIs, lithium or tramadol should not take psilocybin without speaking to a doctor first. If you are unsure how something you take interacts, ask before rather than after.

Storage

Properly dried mushrooms should snap rather than bend. Any give means residual moisture, which means mould risk. Keep them in an airtight container with a desiccant packet, in a dark cupboard at room temperature. Stored dry and dark they hold potency for many months.
