finaplix (tren acetate) can be applief transdermally with plogel or dmso - consensus seems to be about 30-50% as effective as injectible mg per mg. Those who say higher seem to be the ones who have never injected it.
finasteride (propecia/proscar) for hairloss or prostate issues blocking test conversion to DHT by a significant margin - never heard of anyone not taking it orally - not sure of molecular size to make it through skin. Are you sure you mean finasteride?
