The tools are arithmetic
The calculator, the reference library and the handling guides published here perform conversions and present published information. They convert between quantity, volume and concentration; they summarise how a compound appears in the literature; they describe storage chemistry.
They do not select a quantity, recommend a schedule, evaluate a study design, or make any judgement about whether a compound should be used at all. Those are decisions for the person designing the work, and this platform takes none of them.
