I am starting to learn this...my dr had me on 100mg a week, for years, i felt worse, so we upped the dose to 120mg a week, felt even worse after several month, now we dropped back to 100, i am thinkng even going to 80. At 120 my total t before my shot was 1500, at 100mg a week i am still at 1100, and i feel like crap!!
