Testosterone treatments can come in a number of formats such as injections, gels or patches.
Sometimes patients can have a choice to find which work best for them. Each have their own advantages and disadvantages.
Testosterone undecanoate is a popular choice as it is the longest lasting injection available, with injection intervals of between 8 and 14 weeks. The injection is marketed as "Nebido" or "Reandron" in most of the world or as "Aveed" in the USA.
Gel formulations such as "Testim", "Testogel" or "Androgel" are available. These have the advantage of being being able to adjust the dose easily and daily application can in most cases give a very stable testosterone level. In certain places compound testosterone gel preparations are available which can be cheaper than the brand name medications.
