Is a baseline blood test really necessary before starting something like this? Currently on taurine myself.

Same here.

Same for me with taurine, unfortunately.

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

Read methods.

Underdosing and tolerance are indistinguishable from the inside, and everyone picks the flattering explanation. Not on taurine but the pattern is familiar.

Read methods. Five years in on taurine and it lines up.

Narrow conclusion.
