I use Testim 1% 50mg every morning. I use 1 full tube just as the instructions say. What would be the effect if I used only 1/2 of a tube each day? My total testosterone reading has been around 1,000, at the high end of a normal range. I would assume that my testosterone levels may drop a bit, but not sure how much. One advantage is that my cost of testosterone supplements would go down if I can get 2 doses out of one tube.<br> <br> I have one more question. I applied Testim to my abdomen for about 4 weeks and then realized that it is not to be applied to the abdomen. What are the adverse effects of applying Testim to the abdomen? I usually apply it to my upper back/shoulders.<br> <br> Thanks for responding.<br> <br> Gary
