Topical wont do crap, less it has a carrior w/ a molecular weight that willl allow to penetrate skin.
Liver values are transient, ignore them for 2 weeks if your healthy, and they return to normal, even on heavy anapolon/ Dbol cycles of 8 weeks. Liver dammage is way overstated.
For OTC supplements, that problem was solved several years ago by Ergopharm/Patrick Arnold. Most transdermals now are mixed with a base that does allow the ingredient to penetrate the skin as long as the solution in the correct concentration, etc.
Liver values can be transient, but compound the type of stress it experiences from BB "activities" for many many years and next thing you know you have a liver thats starting to fail.
I'd still go with the Gaspari novadex personally, number one because I wouldn't need anything stronger, but also besides being illegal, nolva has shown to cause additional stress on the liver, the last thing you want when trying to recover post-cycle.
Overall, use AI's to get yourself back to normal levels as quickly as possible, but don't stay on them forever, estrogen is actually good for cholesterol levels, joints, libido.
