When the liver has to metabolize 10 mg of methyl 1-test it does not regard delivery method...it simply does not care where it came from since the task at hand is the same.
Granted, if a methylated compound gets around first pass the liver must still contend with it through second, third, or fourth pass. The amount of liver stress is not diminished but rather DELAYED...it will still amount to the same magnitude of liver enzyme elevation regardless of delivery method.
The only thing accomplished is wasting half the active material through the transdermal delivery.
