your doctor should have more information on what to take/what no to take when you mix meds as far as the injection try to get a dose your comfortable and make sure the doctor monitors this ok :)
When I was diagnosed with diabetes, my doctor said my testosterone was low. I had experienced hair loss and I only had to shave every third day. After I started a testosterone treatment, my hair came back and, unfortunately, I had to start back shaving daily.
I forgot to mention that I have lost about 35 lbs. during all of this.
