  We present analytical and numerical properties of the coherently rotating
Affleck-Dine condensate formed along MSSM flat directions with the radiative
corrections to the mass terms included. We analyse the pressure $p$ of the
condensate, which is known to be negative if the potential grows slower than
the field squared. We show that ellipticity of the orbit of the rotating field
also affects the pressure. For circularly orbiting field the $p=0$ while the
smallest negative value, corresponding to the most unstable configuration, is
obtained for a coherently oscillating field. The AD condensate is known to
fragment into non-topological solitons called Q-balls. We also study
equilibration of Q-ball distribution resulting from the fragmentation of the
condensate analytically. We find that equilibration is dependent on the
energy-to-charge ratio $x$ of the condensate. We find the allowed range of $x$
numerically and deduce that equilibration is likely to happen.
