Hi Kendrick, Testosterone is a normal hormone in women's reproductive systems and it starts declining in menopause. Many providers, myself included, prescribe testosterone, esp. for decreased libido. Research has shown cream to be the most effective form. Since the hormone is fat-soluble it can build up in your tissues, esp if you use it for a long period of time. In this case, it can take months for your body to clear it. The best way to test if it's in your system in excess is to do a saliva test.

I went online to find out and don't necessarily have a good answer. Most of the key sites indicate that testosterone therapy for women is not generally recommended, although doctors will prescribe it based on individual cases. These sites generally indicate that the length of time for the testosterone to take effect varies based on the type of testosterone being taken. I'd guess that the length of time it stays in the body also would depend on the type, but I'd suggest talking to your physician or pharmacist about what you're specifically taking.
Take care and keep us posted!
