your estrogen at 40 isnt that bad for 3k plus test ...nothing to worry about... many people never use ai their entire career and never grow a pair of tits.. normally from what ive seen thruout my life..chubby teenagers that had puberty gyno will prone rest of their lives...fat people also tend to have higher lvls of e2.. if ugl test is good for 3k lvls but the ai isnt then thats just a personal preference to people...
