Two years after taking Lupron my testosterone still remained very, very low, approximately fifteen, and I started taking AndroGel, a testosterone replacement, but after five weeks my brests started to enlarge so I stopped the Android gel. I have been told I should have had my breasts radiated before taking the testosterone replacement. Mayo developed a plan for me to now take AndroGel with Arimidex to prevent breast enlargement but Mayo does not have the manpower to implement the plan and the VA will not give me Arimidex because it says studies show it is not effective and I can find no endocrinologist or urologist who will Implement Mayo's plan. I do not want to take testosterone replacement without some breast enlargements preventative like Arimidex. I hope this is helpful to you.
