If you are really concerned about testicular atrophy then you could take HCG during cycle at a low dose at 500 ius week... I did that and it helped...Make sure you use have some nolvadex or liquidex on hand just in case the hcg causes gyno problems...

"Up to a point a man's life is shaped by environment, heredity, and the movements and changes in the world around him. Then there comes a time when it lies within his grasp to shape the clay of his life into the sort of thing he wishes to be. Only the weak blame parents, their race, their times, lack of good fortune, or the quirks of fate. Everyone has it within his power to say, 'This I am today; that I will be tomorrow.' The wish, however, must be implemented by deeds."
