1. A system for dosing a pharmaceutical formulation comprising:
a recirculation system comprising a density flow meter configured to measure a density of the pharmaceutical formulation;
at least one pump fluidly connected to the recirculation system, wherein the at least one pump is configured to displace the pharmaceutical formulation from the recirculation system into preformed molds and is configured to stop displacing the pharmaceutical formulation when the density of the pharmaceutical formulation measured by the density flow meter is below a predetermined threshold.
