Accutane while on PCT

Hy there guys, Im writing for my boy, who did a 12 weeks of test e and deca and got some bad acne on face, chest and back...he is on pct right now (clomid/nolva) and, given the fact all the topic treatment he used didint work at all, today he started taking 20mg ed of accutane (he weighs 84kg, the therapeutic dosage is 0.5mg x kg of bw, so his dose is way smaller than that is supposed to be)...btw, Im a bit scared by lot of comments I read online...about its liver toxicity, etc etc...he bought also some cream for hydritation of face and lips...but my doubt is: is he wrong to use it during pct??? is clomid and nolva harsh on liver too??? Are there among you someone who took tane during pct or cycle??? what suggestions do you feel to give him???

Im a bit afraid right now!
