Testosterone
"I had T levels below 200 and the Doc started me on Androgel 1.62.  I saw minor improvements at 2 and 3 pumps per day, but didn't see normal T numbers until he prescribed a max dose of 4 pumps daily.  I had libido and ED issues that have greatly improved.  The main side effect I have is that I have some body acne on the shoulders and upper chest, I've also had a little more chest hair.  Without insurance and even with insurance the gel can be too pricey for many."
