Abstract We have studied dilepton production in a chemically equilibrating quark-gluon matter produced at RHIC energies. We find that the dilepton yield is no longer a monotonously decreasing function of the initial quark chemical potential. therefore, the dilepton suppression may not be useful as a signature for quark-gluon matter formation.
