I am attaching a stair rail to concrete porch using 4 in Tapcon screws. Just wondering if putting an epoxy in the pre-drilled holes would be beneficial?

If you live where it freezes, you'll want to fill the holes with a stud-setting adhesive. Otherwise water will fill the holes, freeze/expand and crack the concrete.
