Synthol has a lot to do why bodybuilding is fucking awful, these days.
A few guys were using it and eventually fucking up with it way back when, but now we basically just have everybody doing it, everybody being way less detailed in places where they were weak and the judges not placing people accordingly because it's too widespread.
It NEVER looks good. It robs whatever body part of detail. It isn't rocket science, you aren't going to have striated anything when you have oil filling those holes.
Fact is, if Dorian was coming up around now, he'd have had to have tried a bit in his arms.
