Hi all! I have been on 200 mg test cyp (weekly) since March 2011. I am 47 at 6'1, 240 lbs. I have lost body fat and gained muscle mass. My energy level is great and sex drive feels like i'm 20. Labs have been good until yesterday. My urologist said my liver function test was off and he is sending me to get more blood tests. He thinks it may be linked to the test cyp. He backed me down to 150 weekly. My test level was at 680 on the six day when I had blood drawn. Has anyone else had any issues like this. Dr said there is a possibility that I might have to come off the test. The way I feel on testosterone replacement therapy (TRT) I have not felt in 20 years.
