Reconstitution math for one vial and one target dose: the strength to reconstitute to, the bacteriostatic water to add, what one dose reads on a U-100 syringe, whole doses per vial, residual mass and cost per dose. Deterministic arithmetic -- not medical advice, not a prescription, and for relay to a human decision-maker rather than autonomous administration.
