Dose audit

Dose audit — not applicable

This label declares no dosed active ingredients to audit. It is scored on value and formula, not dose integrity.

Spiking check

Not run. No ingredient list was transcribed from this label, so there is no order to check free-form aminos against. That is not a clean result; it is no result.
