Abstract: New version of MSSM scales is discussed. In this version mu << M_{SUSY} ~ M_0 \~ M_{1/2}, where mu is the Higgsino mass, M_0 is the mass scale of sleptons and squarks, M_{1/2} is the mass scale of gaugino. Renormalization group motivation of this MSSM version is proposed. Analysis of Split Supersymmetry ideas in this case together with the Dark Matter arguments results in the statement that the formation of residual neutralino concentration occurs in the high symmetric phase of cosmological plasma. The value of Higgsino mass is estimated. The recharging process for high energy neutralinos in the neutralino-nucleus scattering is considered. There has been reported the possibility to check-up of the model predictions at modern experimental facilities NUSEL and GLAST.
