Recently I worked with a guy that I have worked with a number of times, dieted down a number of times for contests over a period of years. This time he really struggled. Turned out his AI was fake. He had bought it from a research chem site and it  was either ver low dosed or didnt contain adex at all. He struggled to get into shape. We got him tested and estrogen was through the roof. If you have high estrogen, you will be fighting an uphill battle. If you have not gotten your hormones checked, that is the first thing I would do. Get your normal stuff done, liver kidney, red/white blood etc. Plus check thyroid, test, free test and estrogen. This will give you a fighting chance. There is no reason that we ever have to guess if these things are a problem. If you dont have a dr to do this, use a private net based lab company that will write the script for you. Once you find out and everything is stable, come back and lets talk about what it  would take to get you into shape. But first things first. Find out if there is an issue and what that issue is
