I wouldn't even consider using oral AS without Tyler Liver detox. Not after I saw my liver values fall back to normal on 100mg/day of winny within a week. This is not a place to cut corners.
I would never do orals anyway so I can only speak on injectables. No, I don’t use anything. I don’t drink either which by far causes a hell of a bit of damage in itself.
If you are really concerned then get tested and a script for it. There are tons of suggestions and even OTC remedies out there for liver issues. While they can’t hurt you they may give you a false sense of safety. If you are really concerned then the doctor is the only source for information and a fix.
I once did 6 months of dbol at 50-75 mgs/ed without any liver protection. That was before I knew about Tyler's Liver Detox. However, I was fine, in my case. Not that another person wouldn't have had problems, though.
i never use anchilliaries. i still have an unused box of femara i bought some 2 years ago and several cases of clomid and nolva. never took anything besides the AS itself. i don't use anything for the liver when doing orals either. I never drink alcohol or use any other medication, that might help.
