I have to take the patch because my T levels are less than half of low normal. All causes were ruled out. I tried all the alternative meds, exercises, and it stayed below normal for two years. Actually it dropped a little further. Getting old can really suck. Actually I use the patch, not the gel. Androgel is does not work the same as Androderm. Studies have shown the gel is not as well absorbed and does not keep constant serum levels. Androderm on the other hand is very well absorbed and keeps much better serum levels. I researched the other alternatives such as the shots, there is a pill you keep on your gums for a day, pellets, etc. This seemed the best route for me so far. No mood swings after two weeks, and I do notice my muscle recovery to be much faster. True effects I guess will be shown in the lab tests in two months.
