Yeah, if you are doing a heavy oral stack like that they can be used as a good indicator for when you need to back off. I just like when guys are running orals and freak out when their AST and ALT come back double the reference range and I have to tell them to calm the fuck down. You should have been that high anyways if you trained hard. It's when they come back in the upper 200's and 300's that you need to start looking. I was listening to Kurt and Paul talk about in on a podcast, they have seen values as high as 1100 come back on some clients.
