The problem is that Rod's transformation went awry precisely due to not using the serum properly. He said he had chosen a Titan form suitable to fight, but he instead turned into an Abnormal that walked dragging his face on the ground and who was not even interested in the humans around. It would be very difficult to feed him a Shifter in those circumstances; and probably that form was just one of many possible aberrations the serum can cause if misused.
