Your liver values will almost always be elevated on orals, even with proper liver support. Ibuprofen, Tylenol, pretty much anything your filter has to work to break down will cause an elevation in liver values. Even working out alone elevates liver enzymes. Typically it's not a big deal as it's usually temporary...and as long as the values aren't astronomically high. Was your friends liver values elevated to the point where he needed to come off? Or did he just get spooked when he saw elevated values?
