I am going to get some blood work done and would like to know what i need them to look for as far as test levels, free floating levels, leutinizing hormones, or whatnot? I have had absolutely no energy and the sex drive is gone for the past few months. I know something isn't right. If anyone has any ideas it would be appreciated. I'm not on anything and havn't been for about 3 years. I'm 24 so i'm way to young to loose my mojo.
