We use the SU(3) SU(2) U(1) renormalization-group equations to place upper limits on the scale where new physics beyond the standard model must emerge. Our bounds rely solely on the structure of the renormalization-group equations and on the magnitudes of heavy-quark masses. For example, if Σm2q>~(450 GeV)2, new physics must be found below 105 GeV
