Seems as though a combo of both is ideal as the half life for oral trest is very short (usually dosed pre workout).
I think a combo of oral/transdermal trest with superdrol would be a killer cycle, I would for sure have an AI on hand for that one though. I also would probably just run that for 8 weeks max personally.
I also didn't see any word of PCT, I'm assuming you'll be using a SERM.
