Is there anything you are leaving out? Do you consume alcohol, take tylenol etc? Your liver values dropped fast, clearly you have a healthy liver so I think you are jumping to a conclusion when you say "damage" your liver further.

Nolvadex is associated with liver damage over LONG TERM usage i.e. years of therapy with it. Short term acute liver enzyme increases happen with a lot of medications.

Personally, since your liver values dropped so far so quick, I would start PCT because if you don't, you are going to be hurting soon. Another question though, exactly what is your PCT? It almost sounds like HCG is going to be part of your HCG? Also, no Clomid therapy? So post EXACTLY what your PCT would be if you were to start taking it.
