@jeffmarc As usual Jeff , very interesting ! The BAT concept is quite the thing . I was always told taking extra T at any point ( although im not on ADT ) , was like dumping gasoline on a fire ! So reading it , I had to read it three times ! Its appear BAT is successful on many . Great ! I hope it helps some people . Using Estradiol while on ADT is a new wave of discoveries Here is a web site to look at research . I know Dr. Richard quite well . https://estradiolinitiative.org/. Talk soon ! Although Im not on ADT maybe this will help someone ? James from Vancouver Island
