I got a general blood test done when on cycle just a GP did it that didn't know about my use. Had my liver values etc... He told me every thing was excellent that I was in great health. Asked if I ever smoked or drank. I told him never smoked very rarely drank. He said yeah your liver values are some of the best I have seen in a long time. I was on 10 mg of var a day at the time. LOL Even told me my kidney fuctiion was excellent. I had asked because I have always eatin a lot of protein heard rumors etc he told me they were great well with in normal ranges.
