Should i start anavar or winstrol?

I am male, 18-2 yo, 6'1, 220, and am looking for an oral that i can burn fat on while preserving muscle. I read that winstrol works faster and better than anavar but I am on accutane which already puts strain on my liver and winstrol is more harsh on the liver than anavar. Also what other medications will I need to support my liver? I understand that steroids arent healthy and I should wait but im fully committed so theres no point in trying to talk me out of it.
