I would take the narrow conclusion. Broad ones are more interesting and less true.

An inconclusive account is useful if it stops the next person mistaking a story for a controlled comparison.

Sterility is the part people wave through and it is the part that actually bites.

Sleep, food, or the compound? Yes.

A plausible mechanism is not an outcome, and this class is the textbook example. Same for me with lion mane, unfortunately.

Same here.

Stupid question: how do you know whether what is in the vial matches the label at all?

Is a baseline blood test really necessary before starting something like this?

Sleep, food, or the compound? Yes. How long have you been on lion mane?

Narrow conclusion.

Narrow conclusion, briefly right. Broad conclusion, interestingly wrong. I know which I keep choosing.

Test one thing at a time. It feels slower and it is the only way to learn anything.
