Description
We discuss two issues related to the precise determination
of the input parameters of the supersymmetric QCD. As a first
application we propose a consistent evaluation of $\alpha_s$ at the
GUT scale in the MSSM based on three-loop running and two-loop matching.
In the second part of the talk, the evaluation of the bottom
quark mass in the $\overline{\rm DR}$ scheme at the
electroweak/SUSY scale with four-loop accuracy will be considered.
