The damaged creature copies the printed values of Permeating Mass. It won’t copy counters on Permeating Mass or effects that have changed its power, toughness, types, color, or so on. Notably, this means that a creature that becomes a copy of Permeating Mass has the ability to permeate other creatures as well.

Effects that have already applied to the damaged creature will continue to apply to it. For example, if Giant Growth had given it +3/+3 earlier in the turn, it will be 4/6.
