Grinding up a mushroom and putting it in a capsule seems unpredictable, dose-wise.

But a whole batch mixed together? It seems like that would be both testable and predictable. This is the way to go for sure.

From what I remember from 14 years ago when I was more interested in this, psilocybic mushroom strains are, gram-for-gram, almost all equivalent in relative potency.

Drying them to cracker dry, then grinding them up, and encapsulating (optional), is a safe way to dose. It's not unpredictable.

Indeed. This is the right way to do it.

Making it in a test tube is fine, but it's really not needed. Mushrooms are very cheap to grow, and it's not like people need to take big doses daily to get the benefits.

mushrooms aren't as cheap to grow as laboratory yeast cultures already set up to produce quantities of drug of interest.
