We formulate the dynamical symmetry breaking of standard model by a top-quark condensate in analogy with BCS theory. The low-energy effective Lagrangian is usual supplemental relationships connecting masses top quark, $W$ boson, and Higgs boson which now appears as $\overline{t}t$ bound state. Precise predictions for ${m}_{t}$ ${m}_{H}$ are obtained abstracting compositeness condition to boundary conditions on renormalization-group equations full at high energy.
