I have a couple of questions for guys that have used or are using Androgel for HRT. How long do the effects of the gel last? I am trying to split my dose in 2 parts, one in the morning and one in the afternoon. I really feel the effects about two hours after applying, but wonder how long the testosterone levels stay up or how fast it falls in a 24 hour period. Several years ago, I was prescribed Androgel 1%, and was told to apply to my upper arms/shoulders and abdomen. Now I have been prescibed 1.62% and am only supposed to apply it to upper arms/shoulders and NOT to the abdomen. Is this to minimize exposure/transfer to females? If I am showering before bed every night could there be any harm in applying the higher strength to my abdomen as well?
