    According to this curcumin binds to iron in the gut and causes iron deficiency anemia with corresponding drops in RBC and hemoglobins. That explains your results. With my extremely low ferritin I have to rethink. Iron Deficiency Anemia Due to High-dose Turmeric

    My wife is on 10mg test cyp weekly. That dose gives here a total T level of about 120, which is a slightly supraphysiological level. I believe studies have shown that women require a mild supraphysiological level to achieve libido benefits, and her doctor agrees.

    Interesting. My counts have slightly decreased over the past year. I am not sure why and neither are doctors. I also read that a zinc deficiency is a possible cause. I asked my doctor to test for this and he refused.
