We focus on reactions of the type $\\chi \\bar{\\chi}\\rightarrow YY$, where mediators, besides having a finite decay lifetime at rest $\\tau_{\\rm rest}\\lesssim 1$ s, may suffer energy loss in the medium before they decay into photons, $Y \\rightarrow \\gamma\\gamma$. We obtain attenuated gamma-ray luminosities arising from the combination of both effects.
