Due to a long illness, I was effectively chemically castrated and my male hormone levels fell so low they were literally off the charts. I have been having testosterone supplementation now for about six months at 2.5 mg a day, yet not only do I notice no improvement in sex drive from it, but I am even experiencing exactly the opposite of the intended effect -- a reduction of sex drive! If I felt about 5% of my noirmal sex drive before treatment, I have felt absolutely 0% since starting the treatment. A few weeks of treatment at 5 mg a day also made no difference. Has anyone else had this experience with testosterone treatment?
