The other thing I like about transdermal methods (this mostly applies only to gels), aside from the fact that they may work better than shots for me, is that you have a lot more control over levels than you do with shots.

Now, if you are just wanting full T replacement with no strings attached, then the shots make the most sense, assuming they work well enough for you (which they seem to for most people). They are much cheaper and more convenient (only have to be given weekly-monthly versus daily). But if you'd like a little more control over your levels, maybe wanting full T one week, partial T the next, and eunuch status the one afer that, then gels can give you that sort of control. With the long-acting nature of shots, it's very difficult to impossible to achieve any sort of short-term control over levels. You are stuck with whatever the levels are for weeks, and if you decide you want no T for a while, then it will be some time before the shots fully wash out. With gels, otoh, you can vary the levels as frequently as daily if you like, and it is out of your system within a few days. Good stuff for impatient people like me
