HRT - Hormone Replacement Therapy. (ie. testosterone replacement therapy). it is used by men who have naturally low levels of testosterone (for whatever reason) and thus they need an exogenious source of test. so you go to the doc and get a script and then you will get a once a month injection (sometimes every two weeks).
typical doses range from 100mg / month to 400mg / month
these are not doses that one would use for a cycle as you can see. just enough to bring you back to an optimal level or what men should expect at their age.
HRT is the medical abbreviation for Hormone Replacement Therapy, used commonly in females who have had pan-hysterectomies (total hysterectomies). With this procedure the ovaries are removed and the person loses that hormone-producing organ. In order to receive the beneficial hormones, HRT is started....premarin and other conjugated estrogens are used.
