I had this happen to me about 20 years ago when I changed jobs and was denied new life insurance because of high liver enzymes. After going thru the Hep screen and ultrasound noted above, a liver biopsy showed that I have a fatty liver. Mind you at the time I was 5'10" and weighed about 155 lbs, so any mention of "fat" was foreign to me. I now get blood work done 2x/yr. Sometimes its slightly elevated, other times within the normal range (although high end of the range). My doctor at Massachusetts General Hospital isn't concerned and neither am I. If it was someting more serious he says the numbers would be multiples of what they are.
Earlier this year I completed a 8 week cycle of Andromass + AndroBulk and my blood results 4 weeks later were 83 & 61. elevated, but again, only slightly. (my weight is now 195 and a lot of the increase over the years is muscle!)
So all I can tell you is what my doctor tells me: exercise, watch your diet, don't drink in excess and try not to take tylenol.
Take care.
PS: currently just started on a Tren+EPI 2a3a + Methylzine cycle and results after 1 week are better than 8 weeks on AM+AB!
