Multi-Component Calculator
Calculate fixed-ratio blend math for a vial that already contains two to four components. Enter the exact labeled amounts, shared BAC water volume, and either a syringe draw or one anchor-component amount to see how much of every component is present in the same draw.

Each labeled component has its own concentration after reconstitution: component amount divided by the shared liquid volume. A syringe draw is simply a volume, so every component is represented in proportion to that same fraction of the vial.
In the formula above, U-100 units are syringe volume markings, not a universal mass or biological-activity unit.
Because all components share one fixed ratio, solving for the volume that contains a user-entered amount of one component automatically determines the amount of every other component in that same volume. The calculator shows the result without treating the entered amount as a recommendation.
Read the Research & Editorial Policy →It treats a pre-blended vial as several fixed-ratio components sharing the same liquid volume. From the labeled amount of each component and the BAC water volume, the calculator can determine each component's concentration and how much of every component is present in a selected draw volume.
No. In a fixed-ratio pre-blended vial, adding more liquid changes concentration and the volume needed for a given amount, but the ratio between the components remains the same.
Named blend ratios can vary between suppliers. BACToBasics fills the commonly associated component names only and requires the exact amounts printed on the vial label rather than assuming one formulation is universal.
Not in this version. IU measures biological activity and cannot be generically converted to mg or mcg across different substances. The blend calculator therefore limits component amounts to mass units only.
