The Presence Scale is our way of comparing mushroom strains relative to one another within our collection. Ranked from 1 (gentle) to 10 (profound), it offers a simple visual reference for understanding differences in overall strength and character.

Our rankings are informed by measured psilocybin concentration through potency testing, alongside consistent strain traits such as genetics, structure, and long-standing cultural context. Together, these factors help place each strain on the scale in a way that is transparent and comparative.

The Presence Scale is not intended to predict individual experiences or suggest suitability. Instead, it serves as a guiding framework—helping customers navigate the collection with clarity, intention, and respect for the natural variability of mushrooms.

Because fungi are living organisms, slight variations can occur between batches. For this reason, the scale reflects relative placement, not absolute or universal strength.
