Abstract. A local and gauge invariant alternative version of QCD for massive fermions, will be presented. It is underlined that its action includes vertices which eventually could had been overlooked before for the consideration of gauge theories, since at first sight, they seem as breaking power counting renormalizability. However, the fact that those terms also modify the quark propagators, to become more convergent at large momenta, strongly suggests that theory is in fact renormalizable. Accepting this view, it also can be argued that all the four fermions terms constituting the Nambu-Jona-Lasinio models, could be included as counterterms in a slightly generalized renormalization procedure for massless QCD. The possible applications of these properties in massless SUSY models will be underlined.
