It may be possible that your physician believes you are already at an increased risk for blood clots without the Testosterone, and wants to minimize the chances of that occurring. A blood clot that travels to your lungs or brain can be deadly...I might err on the side of caution with that one. That being said, my surgeon advised me to stay on my regular dosing schedule to avoid extreme hormone distress, and I formed no deadly clots. People are all different and your doc likely has a good reason for the recommendation. If you do not agree, seek an opinion from another doc, or at the very least, ask your doc to explain to you exactly why they recommend this course of action.
