Question is, How do you keep your liver values in a safe range. I have been going non-stop for quite some time and my liver values have been high for quite a while. My doc is worried. I am running just strait primo now to try and lower the values. Any pro secrets would be greatly appreciated, as I am now 36 and this is my last run to make it with the big boys. P.S. I know all the common knowledge stuff, so please no noobs chiming in with milk thistle. I have been training for 20+ years and want to cycle for a couple more years.(safely if possible)
