the excess hormones will be recycled via UT meaning that the additional hormones you are taking will stay in your system for longer. This can sometimes be a problem. Does your urine taste any different while on the hormones ? I guess it depends if you need that much hormone in your system. Often what is done is the dosage is halved each successive day until you feel you no longer need it.
I find that any medications I have - most of mine are natropathic in the form of herbs, I can taste the difference in the urine when I take them whereas the urine tastes purer and almost water like when I don't any of the herbs. That is after taking larger amounts.
