An Aoki-Denner form of the renormalization scheme is suggested for the physical amplitudes in the minimal supersymmetric standard model. With the more explicit wave-function renormalization, the scheme is parameterized by the mass of the physical pseudoscalar (MA) and the mass of heavy CP-even neutral Higgs (MH) instead of the conventional MA, as input. The counterterm of is defined on mass shell perturbatively just within the Higgs sector. The renormalization of gauge-scalar mixings are fixed by proper Ward-Takahashi identities. The effect of the reparameterization is also probed to the radiative correction of the mass of the lightest Higgs.
